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.

SOURCE: cannot connect the negative battery terminal without spark or starter turning over

You will need new igniton cylinder. Sounds like you have a short in the cylinder.

SOURCE: I don't understand my wiring diagram.How does the

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.

possible ignition coil itself because tachometer takes signal from ignition coil.you may also have check engine light on too.

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.

Is there a free wiring diagram that show what wire to connect my new winch to


Red is POSITIVE.
Connect to + terminal of battery.
Your winch should be equipped with a fuse.
Do not connect to any of your wiring except battery side of solenoid PROVIDED wire is same gauge or bigger (thickness) than winch wire.
Connect Black to frame or negative battery terminal.

I have a 2013 sportsman Polaris 500. My atv stalled out while riding today and no lights or nothing will come back on. The battery is not dead either. And I checked the fuses?


These machines depend on a good ground. Make sure your ground connections are all clean and tight.... especially the ground wire from the battery to the frame. I recommend removing the battery terminal wires and cleaning the terminals... Also the negative cable that bolts to the frame... remove the bolt and sand the terminal that bolts to the frame. Check for in-line fuses... There is one in-line fuse near the battery!

Head lights will not go on just was working


Check your ground wire connections, if you are sure the bulb the is good. Ground wire connections often corrode or loosen from vibration over time.

Clean battery terminals first, make sure ALL wires are clean and tight! Trace the large hot (+) wire from battery to the solenoid, then trace the large wire output (+) from OTHER TERMINAL directly to the starter connection. The starter is ALREADY grounded.
Get a fresh, fully charged battery, make sure the ignition switch is on, handle bar switch in run position. Push the start button. It should at least turn the engine over!! If this does not work, leave the ignition switch on, jump the two large solenoid terminals with large screwdriver, (SPARKS WILL FLY!!) and see if it tries to start USING THE SCREWDRIVER ONLY!..If it tries to start..or does start, replace the solenoid, (disconnect battery first). If not, check battery amperage and voltage!!

try this and repost

Was installing a winch on my 2009 prowler 700 xtx hooked positive cable to selanoid winch did not work,hooked direct to battery,works,rig wont start


Where did you ground the winch motor? You need a separate, heavy duty, switch with a relay to transfer the positive side voltage properly... DO NOT ground to the battery..use a clean, free of paint, place to ground. You may have fried the solenoid..do not connect the positive side to the solenoid. Direct connection to the + battery from the relay is good with a good waterproof fuse in line. Sometimes I have seen the "maint. free" batteries die when used "wrong" and still show 13 volts+.

Hi Lee,

The starter requires substantially more current (amps) than the little wires and contacts that make up the start button and starter circuit. These small wires power a solenoid (an electro-magnetic switch) when the start button is pressed; which in turn closes a much larger contact that connects the larger battery wires to the starter motor.

You may have a blown fuse or fusible link, bad starter switch button, bad solenoid, broken wire(s) between the starter button and solenoid, poor connections at any of the terminals on these devices or a bad starter motor. Check the these circuits with a volt meter capable of testing 12 VDC or using a test lamp. Start with the one probe of the meter or lamp connected to a good ground or (-) post of the battery. The other probe should see 12 V (+) power on ONE of the starter button wires and on BOTH when the button is pressed. If not, work your way back to a bad connection or cut wire. Next, locate the solenoid. There should be two heavy cables and one or two smaller wires entering. The smaller wire is from the start button. Power 12V + should be on it when the button is pressed. If there are two smaller wires, one is probably ground or (-). If no power, check the wire for damage, etc. by following the wire back to the starter button. Once you have 12 V + starter circuit working into the solenoid, go to the next step.

Next, check the two heavy cables on the solenoid. One should have 12 V + power on it all the time and the other should have power only when the starter button is pressed. If you do not have power on one of the cables all the time, there is a bad connection,etc. between the solenoid and the + battery post. Check fuses, connections, etc. and make repairs. With power on one cable, press the start button A working 12 V starter circuit is required for this to work. If no power on the other heavy cable, the solenoid should probably be replaced. If you do have power out, it it still won't crank - check the cable between the starter and solenoid. Repair or replace as needed. If cable is good, the problem is likely to be the starter itself.

Good luck!

When I push the starter button the solenoid clicks,starter does nothing.if I cross the 2 threaded bolts that extend out from the solenoid the starter engages? I just replaced the solenoid and at first it...


Just because it's new, doesn't mean it works.
This is why cars get recalled.

The iron-clan test of a non-working solenoid is to cross the relay terminals. If you do and it starts.. it's bad.

Take it back. you purchased a dud. It happens.
