SOURCE: no turn signals 2001 fxsts

More than likely, dampness has caused corrosion to form between the turn signal BULBS and the turn signal bulb SOCKETS. FOLLOW THIS PROCEDURE: Remove turn signal bulb from its socket, spray the socket with ELECTRICAL CONTACT CLEANER, wipe off bulb terminal end with a cloth that has been sprayed with Electrical Contact Cleaner, put a little DIELECTRIC GREASE on the terminal end of the bulb, Reinstall the bulb into its socket, Remove any fingerprints from bulb with a soft cloth. Be sure to note that the Bulbs do not have broken filaments, Replace the Bulb if it does. That SHOULD take care of your Turn Signal Problem. IF NOT, then further diagnoses of the FLASHER UNIT is required, and I can help you further with that if needed. AS FOR THE TACH PROBLEM, Disconnect any wire lead within the TACH unit that you can find that are easily dissconnectable, and with the same procedure described earlier, spray out with Electrical Contact Cleaner, and reconnect the plugs. That SHOULD solve your problem. If not, contact me further. GOOD LUCK. -Dr.Mark

SOURCE: wont fire turns over faster than normal

if you still havent started the bike yet from sitting.then i dont think the choke has anything to do with your problem.but ether way take the plugs out.I think your piston rings are frozen from sitting.did u winterrize it?with the plugs out pour a little auto trans fluid in each cylinder.very little.now crank the bike over to coat the cylinders. becareful it could be messy now let the bike sit overnight.the next day crank bike over again.but this time for a few tries.then install fresh plugs.and try to start it.p.s there will be white smoke from the transmission fluid. that will go away in a couple of minutes.then all should be good.

SOURCE: My 2002 electra glide classic head light flickers

The voltage regulator is starting to fail. The headlight is flickering with the pulsing of the alternator when the motor is running. If you have had your Harley long enough, you are familiar with the "potato potato" sound when idling. That sound is the result of the 45 degree angle of the cylinders and the flywheel surging, which is absolutely normal. So, when the engine is idling and the alternator is surging in time with the motor, the voltage is surging as well; the voltage regulator is what steadies the power so the bike puts out steady light.

So now we are back to beginning of my answer to you; the voltage regulator is failing and that is what is causing your lights to flicker.

The voltage regulator is mounted on the bottom front outside part of the frame. An easy way to locate it is to get down there and find the oil filter, there is a box there with fins (heat sinks) right there. Change that and you will not have a flickering problem.

2007 chevy equinox, running lights are not working, fusses work fine, what else would be the problem?


The problem is your not familiar with electronic's on modern automobiles . Module controlled systems . BCM - body control modules .
The park lamps consist of the park, tail, marker and license lamps. These lamps are illuminated any time the headlamp switch is in the PARK, ON position, or anytime the body control module (BCM) illuminates the headlamps. The PARK fuse in the fuse block - instrument panel (I/P) supplies voltage to both the coil and switch input side of the park lamp relay. The BCM controls the park lamp relay by grounding the park lamp control circuit energizing the relay.

PCB Relays
This vehicle is equipped with the following PCB mounted relays. High Beam, Low Beam, DRL, Fog Lamp, Park Lamp, Stop Lamp, and Horn relay. They are directly soldered to the underhood fuseblock circuit board. A failure of one of these relays will require the whole underhood fuseblock to be replaced.

Your best bet have a qualified repair shop diagnose the problem . Could have DTC'S - diagnostic trouble codes stored in the BCM For circuit faults .

Auto lights won't turn off on a 2011 Chevy Traverse even after 10 minutes


Well Jeni there are a few thing's that could be wrong , the headlamp switch , the BCM -body control module -a electronic control module . There are relays involved also ,but don't think there at fault . To be sure you need to do some electrical test to know for sure ! I suggest you take it to a ASE certified repair shop that has the knowledge , tools an service info - wiring diagrams etc.. ! Oh and a scan tool that can extract DTC'S from the BCM there could be a diagnostic trouble code pointing to the problem !

1. Headlamps Always On

2. Headlamps Inoperative From Switch

3. Unable To Turn OFF Automatic Headlamps

4. Park Lamps Inoperative From Switch

5. Park Lamps Always On
When the headlamp switch is in the OFF position, the body control module (BCM) receives a ground signal through the headlamp switch OFF circuit and an open signal on the park lamp ON circuit and headlamps ON circuit. When the headlamp switch is in the PARK or HEAD position, the BCM receives an open signal through the headlamp switch OFF circuit and a ground signal through the park lamp ON circuit or headlamp ON circuit.
Circuit/System Testing

  1. Ignition OFF, disconnect the harness connector at the headlamp switch.
  2. Verify that a test lamp illuminates between the ground circuit terminal 8 and B+.
  3. ?‡'
    If the test lamp does not illuminate, test the ground circuit for an open/high resistance.

  4. Ignition ON, verify the scan tool Auto Hdlp. Disable Sw. parameter is Inactive.
  5. ?‡'
    If not the specified value, test the signal circuit terminal 3 for a short to ground. If the circuit tests normal, replace the BCM.

  6. Verify the scan tool Headlamp Switch parameter is Inactive.
  7. ?‡'
    If not the specified value, test the signal circuit terminal 1 for a short to ground. If the circuit tests normal, replace the BCM.

  8. Verify the scan tool Parklamp Switch parameter is Inactive.
  9. ?‡'
    If not the specified value, test the signal circuit terminal 2 for a short to ground. If the circuit tests normal, replace the BCM.

  10. If all circuits test normal, test or replace the headlamp switch.
If the BCM needs to be replaced , it has to be programmed . The dealer is pretty much the only place to have that done at ! There are other places ,you have to look in the phone book or inquire at local repair shops . Some towns ,city's have mobile repair guy's that do flash programming of modules etc... Good luck hope I gave you some insight on the problem ! I tell people these thing's an it's like they don't believe me , I see they repost the same question . I started working as a Technician in 1984 at a Chevy dealer ship an have worked at Cadillac , Pontiac , GMC dealer ships ! I see all to often people trying to fix these type of problems by just replacing parts not knowing what they are doing an wasting there money an later bring it to the shop anyway ! So I hope you make a good decision an take to a qualified repair person or shop !

Why does my 1999 chevy malibu headlights turn on by them self in middle of night


You have a gremlin ! No , just kidding . No it's not the ignition switch ! The headlamps right an left have there own fuse in the under hood fuse box . LH HDLP - RH HDLP . Power direct to the head lamps an they ground through the headlamp switch when placed in high or low beams . Next time they come on wiggle the headlamp switch an see if they go out ! Does your vehicle have auto lights ? Day time running lamps ? The BCM - body control module controls Automatic lamp control !
Battery voltage is applied to the headlamp bulbs at all times. The headlamps are controlled by supplying the ground for the lamps through the turn/headlamp switch assembly or the body control module (BCM). When the turn/headlamp switch is in the ON position, the ground is supplied through CKT 150.
The BCM controls the daytime running lamps (DRL). The system allows the headlamps to operate at a reduced intensity under the following conditions:
?€¢
The engine is running.


?€¢
The transaxle is not in the PARK position.


?€¢
The normal headlamps are turned OFF.

The BCM activates the system by grounding CKT 592. This action energizes the DRL relay. This condition allows a reduced voltage to flow to the headlamps. When the headlamp switch is turned to ON, the headlamps operate normally.
The parking brake provides an input to the BCM. When the parking brake is engaged, the DRL remain disabled until the parking brake is disengaged.

Why wont the headights or running lights work on my 2002 Buick LaSabre?


There are several reasons why your headlamps an running lights don't work , the headlamp switch is a good one ,plus relays an the DIM - dash integrated module an associated wiring ! Here is how the headlamps work , right out of Buick factory service info !
The dash integration module (DIM) provides battery positive voltage to the signal circuits of the headlamp switch. The signal circuits include the headlamp switch headlamps on signal, the flash to pass switch signal and the high beam input. With the headlamp switch in the ON position, a ground path is available for the headlamp switch headlamps on signal circuit of the DIM through the headlamp switch. The DIM provides ground to either the headlamps high beam relay control circuit or the headlamps low beam relay control circuit of the low beam circuit. The position of the headlamp dimmer switch determines which relay control circuit has ground. The DIM supplies battery positive voltage to the relay control circuits, if the headlamps are necessary. The fuse block - underhood supplies battery positive voltage to both relay switch circuits. When the low beam relay control circuit is energized, current flow is to both low beam fuses and to the low beam headlamps. The headlamps have ground at G103 and at G401. When the headlamp high beam relay control circuit is energized, current flow is to both high beam fuses and to the high beam headlamps. The high beam circuit is divided into a left and right side circuit. The current flow of the left high beam is from the fuse to the left high beam lamp. From the lamp, the current flows to the normally-closed contact of the DRL relay to G103. The current flow of the right high beam is from the fuse to the right high beam lamp. From the lamp, the current flow is to ground at G401. When the headlamp dimmer switch lever is pulled toward the driver, the flash-to-pass switch closes. This grounds the DIM flash to pass switch signal circuit. In response to this input, the DIM energizes the HDLP HI BM relay. Both high beams remain on until the driver releases the switch handle. If the low beam headlamps were on during a flash to pass operation, the low beams remain on. The headlights may be switched to high beam with the opposite movement of the headlamp dimmer switch lever.
By running lights , do you mean park lamps or day time running lamps ?
Park, Tail, License and Marker Lamps
The park lamps, including the license lamps, are turned on when the headlamp switch is placed in the PARK or ON position or anytime the headlights are requested. The fuse block - rear supplies battery positive voltage to the switch contacts of the Park LP relay. When the headlamp switch is in PARK or in ON, the park lamp switch on signal circuit of the DIM has a ground path. The DIM provides battery positive voltage to the control circuit of the Park LP relay. When the park lamps and/or the tail lamps are ON, the DIM energizes the park lamp relay control circuit. This closes the switch contacts. Current flows from the Park LP relay to the LH PARK LP and the RH PARK LP fuses. From the fuse, the current flows to the park lamps. The left park lamps are grounded at G103, G401 and G402. The right park lamps and the right tail lamps are grounded at G103 and G401. The DIMR fuse supplies battery positive voltage to the license lamps and to the DIM instrument panel lamp fuse supply voltage - 1 circuit, for interior lamps dimming. The license lamps are grounded at G401.
The best advice I can give is that you take this to a ASE certified professional repair facility unless your a qualified automotive electric repair person !
Diagnostic Starting Point - Lighting Systems
Begin the system diagnosis with the Diagnostic System Check - Lighting Systems . The Diagnostic System Check will provide the following information:
?€¢
The identification of the control modules which command the system


?€¢
The ability of the control modules to communicate through the serial data circuit


?€¢
The identification of any stored diagnostic trouble codes (DTCs) and their status

The use of the Diagnostic System Check will identify the correct procedure for diagnosing the system and where the procedure is located.

Under system click on lighting ,then under subsystem click on turn signals . Click the search button then the blue links .Check power an ground circuits ! This is how we diagnose electrical faults , not just replacing parts .

Turn Lamps
Voltage is applied through the TURN fuse and the turn/hazard flasher when the ignition switch is in the following positions:
• RUN
• BULB TEST
• START
The voltage travels to the contact in the hazard switch. The hazard switch is located in the turn/hazard-headlamp switch assembly. This contact is normally closed.
When the left turn signal is turned on, voltage is applied to the following components.
• The left turn indicator
• The left front park/turn lamp circuit 14
• The left rear turn lamp circuit 18
The turn lamps turn on immediately. The current flow heats up the timing element. The timing element is located in the turn/hazard flasher. The timing element repeatedly opens and closes the circuit. This action causes the turn lamps to begin flashing.
The voltage that is applied to the left front park/turn lamp is also applied to the left front marker lamp. If the headlamp switch is in the OFF position, the left front marker lamp will find a path to ground through one of the following lamps. The following lamps provide low resistance paths to ground:
• The right front marker lamp
• The right turn indicator
• The right front park/turn lamps
• The left front park/turn lamps
The left front marker lamp flashes with the turn lamps. The voltage drop across the marker lamp is much higher than the voltage drop across the other lamps. The lamps that are used for the ground path will not flash.
When the headlamp switch is in either the PARK or HEAD positions, voltage is applied through the following components:
• The EXT LP fuse
• The marker lamps
• The park lamps
When the left turn signal is turned on, the left marker lamp will have voltage at both connections. The left marker lamp does not light. When the turn/hazard flasher stops the voltage to the turn lamps, the marker lamp is grounded through the turn lamp. The marker lamp does not go on. The left front marker lamp flashes in the following manner:
• The left front marker lamp flashes on when the turn filament of the left front park/turn lamp goes off.
• The left front marker lamp flashes off when the turn filament of the left front park/turn lamp goes on.
Voltage is applied to the right lamps in the same manner, when the right turn signal is turned on.
Hazard Lamps
Voltage is applied at all times through the following components to the normally open contact of the hazard switch in the turn/hazard-headlamp switch assembly:
• The STOP HAZ fuse
• The turn/hazard flasher
When the hazard switch is turned on, voltage is applied to the following components:
• The front turn lamps
• The rear turn lamps
The following lamps flash on and off:
• All of the turn lamps
• Both of the turn indicators
The front marker lamps flash with the hazard lamps on, just as the front marker lamps flash when the turn lamps are on. If the headlamp switch is in the OFF position, the front marker lamps flash on when the hazard lamps are on. The front marker lights will flash on when the hazard lamps are on if the headlamp switch is in one of the following positions:
• PARK
• HEAD
When the hazard lamps are on, the following conditions apply:
• The turn circuit is always open.
• The turn/hazard flasher controls the lamp.
Park/Marker Lamps
Voltage is applied through the EXT LP fuse, to the headlamp switch at all times. Voltage is applied to the park lamps and the marker lamps when the headlamp switch is in the following positions:
• PARK
• HEAD
The front marker lamps are grounded through the turn filament of the respective front park/turn lamp. The front marker lamps light as a result.
Stop Lamps
Voltage is applied through the STOP HAZ fuse to the brake switch at all times. When the brake pedal is depressed, the brake switch closes. This action applies voltage through the turn/hazard-headlamp switch assembly to the following lamps:
• The high mounted stop lamp assembly
• The left tail/stop-turn lamps
• The right tail/stop-turn lamps
