Question about Honda CB 125 T Motorcycles

Open Question

Is it possible to connect a tachometer to a honda atc 125m?

Ive connected the positive cable to a switched positive terminal and the ground wire is connected to a ground and the gauge light wire is connected to the switched positive terminal as well. the light works and the tachometer gets a signal ,only when i connect the wire that sends the signal to the tachometer, to the spark plug wire but if i do this the engine shuts off because it grounds out the spark plug. ive tryed connecting this wire to the negative side of the ignition coil,like the instructions said, but the tachometer doesn't register a signal where do i connect this wire to get a signal without shutting off the engine? ive already got a manual.

Hi and welcome to FixYa,

If the starter relay in your version uses blue / white and red / white wires, then to my understanding, connection would be:

  • blue / white - goes to the start switch and is supplied with +12 on starting;
  • red / white - goes to the starter circuit cut-out relay. This cut-out relay controls whether the starting relay gets a ground based on neutral/gear and clutch lever conditions.

Good luck and thank you for asking FixYa.

Hi and welcome to FixYa,

Pls see your other post, but basically:

  • in most, one end of the red wire is connected straight to the battery's + terminal. The other end of the red wire goes to the main fuse;
  • the black of course as you posted goes to the ground;
  • interchanging the 2 wires from the starter relay would make no difference;
  • the starter relay is not directly grounded;
  • the starter relay's + wire goes to the starter button;
  • the starter  relay's - wire goes to starter cut-off activated by safety interlocks (neutral and clutch lever).

Good luck and thank you for asking FixYa.

I would be thinking that there is a good chance that you need to be checking out replacing the computer, if you aren't getting any communication with the proper scan tool then the computer isn't communicating with anything in the vehicle...... I would have guessed first off that the ignition control module might be bad but that is obviously part of the computer also, I would be looking in that direction.

No spark from coil to distrubuter


Disconnect the ignition coil output wire at the distributor cap.
Connect a spark plug to the end of the ignition coil output wire which you just disconnected.
Connect a ground wire to the threaded portion of the spark plug.
Disconnect the ignition coil ground wire from the negative terminal on the coil (Green Wire).
Connect one end of a ground wire to the ignition coil negative terminal.
Turn the ignition switch to the ON position.
Tap the other end of the ignition coil ground wire jumper on an good grounding point (for example the battery negative terminal) and look for sparks at the spark plug that correspond to the frequency of your tapping of the ground wire.
If you have a good spark at the spark plug, the ignition coil is good.
If you don't get a good spark, check for approximately 12 VDC from the coil positive terminal (black wire) to ground with the ignition switch in the ON position. You should also get approximately 12 VDC from the coil negative terminal (Green wire) to ground
Ignition Coil Resistance Check

In addition to the test above, you may elect to perform an ignition coil resistance check as confirmation of the coil's condition.

Check the ignition coil primary coil resistance by connecting an ohmmeter between the positive (Black wire) and negative (Green wire) terminals on the coil. The resistance should be 0.4 to 0.6 ohms.
Check the ignition coil secondary coil resistance by connecting an ohmmeter between the coil output terminal and the ignition coil negative terminal. The resistance should be 5000 to 7200 ohms.

You may have a bad coil or bad ground or wire connection

Anyone have a wiring diagram or know how to hook this up ?


Black and red are pretty standard for negative & positive battery terminals.
There is likely a model number (pic isn't good enough to see the finer print) on the label but the larger numerals are probably serial numbers and without the model number, you may have a problem finding the exact installation info you want.

The link below has illustrations for a different model but manufacturers will generally stick with a wiring code to make installation and even production simpler:

That company does not have the web 'presence' they should have by now.

My speedometer not working? is it cause of the after-market radio i put in be the reason.. mitsubishi galant 2002 6 cylinder


So we can rule out the speed sensor and its circuit to the PCM.

I just checked through another area of my database and it seems the speed sensor is systated as on the side of transaxle, near firewall, maybe you can dheck that out to confirm, just out of curiosity and for future reference and some portion of testing requires unplugging the conections.

Anyway I will provide a complete diagnostic pocedures for you to check through and hope an answer is found.

PS. After going through the diagnostic procedure, I believe your radio is the cause of the problem. Refer to # 10

SPEEDOMETER DOES NOT WORK

1. Connect scan tool to data link connector, check for Diagnostic Trouble Code (DTC). If DTC P0500 (Vehicle Speed Sensor) is set, diagnose this DTC first. Go to step 6 . If DTC P0500 is not set, go to next step.

2. On Eclipse, if trip odometer is not working normally, go to next step. If trip odometer is working normally go to step 5. On Galant, if tachometer is not working normally, go to next step. If tachometer is working normally, go to step 5

3. Disconnect instrument cluster connector. Turn ignition switch to ON position. Connect DVOM between ground and instrument cluster connector terminal No. 52 (Black/White wire) on Eclipse or terminal No.29 (Black/White wire) on Galant. If battery voltage is present, go to next step. If battery voltage is not present, check harness connectors and harness wiring between instrument cluster and ignition switch for damage. Repair as necessary.

4. Using a DVOM, check resistance between ground and instrument cluster harness connector terminal No. 34 (Black wire) on Eclipse or terminal No. 30 (Black wire) on Galant. If resistance is less than 2 ohms, replace instrument cluster printed circuit board or speedometer and tachometer. If resistance is greater than 2 ohms, check instrument cluster connector and harness wiring. Repair as necessary. If connector and wiring are okay, go to next step.

5. Disconnect vehicle speed sensor connector and instrument cluster connector. Turn ignition switch to ON position. Connect DVOM between ground and harness side of instrument cluster connector terminal No. 29 (White/Blue wire) on Eclipse or terminal No. 16 (Yellow/Black wire) on Galant. Voltage should be 5 volts. If voltage is okay, repair or replace instrument cluster printed circuit board or speedometer and tachometer. If voltage is not 5 volts, check instrument cluster connector and harness wiring. Repair as necessary. If connector and wiring are okay, go to next step.

6. Disconnect vehicle speed sensor harness connector and connect DVOM to harness side. Check vehicle speed sensor power supply voltage between terminal No. 1 (Black/White wire) on Eclipse or (Black/Blue wire) on Galant and ground. Battery voltage should be present. If voltage is okay, go to next step. If voltage is not present, check vehicle speed sensor harness connector and wiring. Repair as necessary.

7. Using DVOM, check resistance between ground and vehicle speed sensor harness connector terminal No. 2 (Black wire). Resistance should be less than 2 ohms. If resistance is greater than 2 ohms, check instrument cluster connector and harness wiring. Repair as necessary. If connector and wiring are okay, go to next step.

8. Disconnect vehicle speed sensor harness connector. Connect DVOM between ground and harness side terminal No. 3 (White/Blue wire) on Eclipse or (Yellow/Black wire) on Galant. If 9 volts are not present, check vehicle speed sensor harness connector and wiring. Repair as necessary. If 9 volts are present, go to next step.

9. Check harness wiring between vehicle speed sensor connector to radio and tape player connector, auto-cruise control ECU ECM (M/T) or PCM (A/T) connector and instrument cluster connector. If connectors or wiring are damaged, repair as necessary. If connectors and wiring are okay, go to next step.

CAUTION: To prevent damage to scan tool, always turn ignition off before connecting or disconnecting scan tool.

NOTE: If ECM (M/T) or PCM (A/T) is replaced, immobilizer-ECU should also be replaced. Each ECM (M/T) or PCM (A/T) has an encrypted code for immobilizer-ECU, and is registered in immobilizer-ECU.

10. Connect scan tool to data link connector. Turn ignition switch to ON position. Read DTC. Disconnect radio and tape player connector. If DTC P0500 does not reset, replace radio and tape player. If speedometer does not work, disconnect auto-cruise control ECU connector. If DTC P0500 does not reset, replace auto-cruise control ECU. If speedometer does not work, disconnect instrument cluster harness connector. If DTC P0500 does not reset, replace instrument cluster. If DTC P0500 resets when any connector is disconnected, replace ECM (M/T) or PCM (A/T).

The Casablanca 88U33M Scandia Ceiling Fan only has three wires, a black, a white, and a green wire (ground). How do you wire the fan and light on seperate switches?


If you want to control both the light and the fan using 3-ways, then just wire 2 sets of the 3-way circuits. For this you need two sets of 3-wire between the switches, and one 3-wire cable from the switch location to the fan/light box.

At box #1 (a 2 gang box), you will run a power cable (marked cable #1) into it. From there you run 2 sets of 3-wire cables (identified as cable #2 & cable #3) to the other switch location, which will also be a 2-gang box (box #2).

Also from box #1, you will run a 3-wire cable (cable #4) to the fan/light box (box #3).

Hook up is as follows:

Box #3: connect black of cable #4 to black (fan), connect red of cable #4 to blue (light), connect white of cable #4 to white (fan/light), and connect the bare to the green.

Box #2: Connect white of cable #2 to identified terminal on 1st 3-way switch (#3). Connect red & black of cable #2 to the remaining screws of 3-way switch #3. Next connect white of cable #3 to identified terminal of 2nd 3-way switch (#4), and connect black and red to remaining screws. Tie all grounds together and terminate to both switches.

At box #1, connect black from cable #1 to whites in cables #2 & #3, using a wirenut. Connect white in cable #1 to white in cable #4. Connect black and red in cable #2 to 3rd 3-way switch (#1) and connect black and red in cable #3 to 4th 3-way switch (#2). Connect black in cable #4 to identified terminal of 3-way switch #1, and connect red in cable #4 to identified terminal on 3-way switch #2. Tie all grounds together and to the switches

The cigarette lighter in my car is not hooked up to anything. im wanting to know i i hook it up?


get an inline fuse holder and run it under the dash and out a grommet on the firewall. connect it to the positive (red) connector on the batter. than with the ground (black) connect that to a screw that goes in the body somewhere. use a 14 gauge ring terminal connector on both ground and positive wire. use 15amp fuse in in line. cylindrical, atc, or mini atc will do. since it is not hooked up to an ignition source it will work when the car is off. it will only have power when engaged. don't worry about power drain.

84 goldwing aspencade 1200a while cranking motor ran battery down ..charged back up now turn ignition on apply clutch hit the starter button and nothing have heard a click in the resistor a couple of...


If you heard a click when the starter button was pressed but the starter did not run then the problem most likely lies with the starter solenoid or the starter itself. Check the starter itself by connecting a heavy jumper cable from the positive of the battery to the terminal on the starter motor. If the starter cranks, then the starter is okay and the problem is the solenoid switch.

When performing the above check, first make sure the bike is in neutral or the clutch lever is pulled. When you make the connection with the jumper cable there may be some sparking because the starter draws a lot of amps.

To check the solenoid there should be 3 or 4 terminals on it. There will be one or two terminals that have smaller wire/s attached and there will be two larger ones that have a positive wire from the battery attached and the other one connects to the starter positive terminal. Connect the negative terminal of a dc voltmeter to the bike frame and the positive lead to the terminal on the solenoid with the small wire attached. (If there are two small wires, one of them connects to ground and the other one comes from the starter button.) If you observe 12 volts at this solenoid when you attempt to start the engine the the problem is in the solenoid or starter. Since we already checked the starter then the problem would have the be inside the solenoid switch.

IF YOU DO NOT see 12 volts at the small terminal/s of the solenoid when you attempt to start the engine then the problem is an open in the wiring path between the battery positive and the solenoid switch. This could be the ignition switch, a loose, broken or burned wire, neutral or clutch interlock switch or anything else in that wiring path that is open.

Ok this is a GFCI switch receptacle combo. You will connect the incoming cable to the incoming terminals on the Recptacle. White goes to Line (silver) terminal Blk goes to Line (brass) terminal. For the light connect the white to the load terminal (silver) Then take a short black wire and connect from the Load (brass) terminal to one of the switch therminals. Connect the remaining outgoing black wire to the other switch terminal (at bottom of switch) connect both green wires to green ground screw. (best to "pigtail" ground wires so only one wire on terminal. This will give lights GFCI protection also good for hanging lights in a bathroom.

Battery to starter motor.


Just to be clear, the starter should have a large terminal (where the battery cable connects) and a smaller terminal (where the activation wire connects)
The starter is grounded via the mounting bolts.
The activation wire runs from the starter to the starter switch.

GENERATOR OUTPUT LINE VOLTAGE DROP TEST

This test determines the condition of the wiring from the generator "B" terminal to the battery (+) terminal (including the fusible link). 1. Be sure to check the following before testing: a. Generator installation and wiring connections b. Generator drive belt tension c. Fusible link d. Abnormal noises from the generator while the engine is running. 2. Turn the ignition switch to the OFF position. 3. Disconnect the negative battery cable. 4. Disconnect the generator output wire from the generator "B" terminal. Connect a DC test ammeter with a range of 0-100A in series between the "B" terminal and the disconnected output wire. (Connect the (+) lead of the ammeter to the "B" terminal. Connect the (-) lead of the ammeter to the disconnected output wire.) An inductive-type ammeter which enables measurements to be taken without disconnecting the generator output wire is recommended. Using this equipment will lessen the possibility of a voltage drop caused by a loose "B" terminal connection. 5. Connect a digital-type voltmeter between the generator "B" terminal and the battery (+) terminal. (Connect the (+) lead of the voltmeter to the "B" terminal. Connect the (-) lead of the voltmeter to the battery (+) cable.) 6. Reconnect the negative battery cable. 7. Connect a tachometer or the scan tool. 8. Start the engine. 9. With the engine running at approx. 2500 rpm, turn the headlights and other lights on and off to adjust the generator load on the ammeter slightly above 30A. Limit: max. 0.3V When the generator output is high and the value displayed on the ammeter does not decrease to 30A, set the value to 40A. Read the value displayed on the voltmeter. In this case the limit becomes max. 0.4V. 10. If the value displayed on the voltmeter is still above the limit, a fault in the generator output wire may exist. Check the wiring between the generator "B" terminal and the battery (+) terminal (including fusible link). If a terminal is not sufficiently tight or if the harness has become discolored due to overheating, repair, then test again. 11. After the test, run the engine at idle. 12. Turn off all lights and turn the ignition switch to the OFF position. 13. Disconnect the tachometer or the scan tool. 14. Disconnect the negative battery cable. 15. Disconnect the ammeter and voltmeter. 16. Connect the generator output wire to the generator "B" terminal. 17. Connect the negative battery cable.

Hi, I bought the Stunner CBF bike 4 years ago. It Hi, I bought the Stunner CBF bike 4 years ago. It was fine up to 40,000 kms. And after 40,000 kms its starts to smoking. So i replaced the ring and piston with original parts but it didn't work well and still smoking and again the technician open the bike and they said that it is the piston problem and they said that it should be replaced but not with the original parts and they replaced the ring and piston with 50mm size of Mahal brand. I have replaced all the parts like ring, piston, valve and other supporting parts but still my bike smoking when i accelerate above 60km/h. When i ride bikes in hilly areas with my friends behind then pick up is very less and its bikes smokes blue. My silencer gets wet and when the bike cool down then the silencer gets dry. When i check the engine oil it is fine up to mark of the leveler. So i am confuse what is the problem. For 8 to 10 times i used Sarvo, Enoc and Zic engine oil. Now i am using Honda engine oil in a gray bottle pack. The technician said that the parts of honda is not good enough as before. These are all made in china so that the problem occurs. So that they replace the Mahal brand ring and piston. Now my bikes traveled nearly 50,000 kms (49,800 kms). And one thing i didn't give my bike to the showroom for the replacement of ring and piston. I gave it to the reputed technician in town. I think this time i will get proper answer for my problem. Thanks
