SOURCE: need wire diagram for the turn signal switch.

your wires are crossed/shorting somewhere, probably in the headlight. remove the light to get to all the wires. you should be able to see which colors go to which side, also look at the wires coming from the turn signals both front and rear lefts will be same color and the rights will be another color. you should be able to tell by looking inside the switch which side is which color and which one is the feed to the switch

SOURCE: replacing signal lights on a 1992 sportster that

The two wire system is for a turn signal only unit. The three wire unit has a turn signal and a running light in it. Remove the turn signal lense and you'll probably see a dual filament bulb. The two wire system is shown as an "International" wired model according to my book. One wire is the "hot" wire (Brown) and the other is a ground or earth wire (black) on the bike. On the turn signal unit, probably all wires are black. You can use a VOM to determine which wire is the ground wire or you can just try hooking them up in different ways until you find one that works.

SOURCE: left turn signal not working proper

Turn signals flashing is the confirmation of alarm system being on.I thought both sides flashed but if alarm is faulty guess that's messed up too. Try starting from stratch with alarm,disarm it[disconnect neg wire at battery]then reconnect wire and when that sets off alarm turn it off in normal way.That should get things back on track.Plus,try replacing the flasher unit,don't know why this works but I've heard of it.

Sorry but I don't have a wiring diagram that I can send you but I may can offer a bit of help.

Your passing lamps are simply wired into a hot circuit somewhere. A lot of schematics don't show them because they are considered "add ons". They also may have a fuse inline with the "hot" wire. They have only one wire that connects them to the bike with the rest being inside the "light bar" itself. Find the wire coming out of the center of the "light bar" and trace it back to where it hooks up. Sorry but that's the best I can do on this one.

On your front brake light, there is a switch located inside your right hand switch housing where your throttle is located. It is a plunger type switch that is activated when you pull the front brake lever. A simple test of the switch is to loosen the bolts of the master cylinder and slide it towards the center of the handlebars. If the switch is good, the brake light will come on. If the switch is bad, it will not.

To get to the switch, you'll have to take the right hand switch housing apart. First, loosen the throttle cables at the adjusters and then remove the two bolts that hold the switch housing halves together. Carefully open up the switch housing. You will see the small switch in the front of the housing. You'll have to desolder the wires, replace the switch with a new one, and resolder the wires to the new switch.

Reassembly is the reverse of the disassembly. Make sure you slide the master cylinder all the way back against the switch housing or the brake light will stay on constantly. Readjust the throttle cables and check for proper operation. You don't want your throttle sticking.

Good Luck
Steve

I have a 2002 suzuki intruder volusia vl800. When I got it it has led rear brake and taillights no turn signals. So it only had 3 wires hooked up. I got a tail/brake/turn signal combo led it has 5...


so is this the reals story?
  1. I modified my car,
  2. now it dont work?
is that it? we cant help you fix a car that is not stock
sorry, the books only cover stock, so if walk that path, then get pro
help that is willing to work on hacked up cars.

put it back to stock
bingo it works
now break it again, repeat ,wash and repeat.

YOU DO know that many cars will not run LED , correctly right
and blinkers top that list.

there are 2 cures,
1: back to stock
2: get dummy load resistors to fool car in to thinking blinkers are stock.

most blinker modules, do a dance (actup) on purpose.
the warn you that a light is dead or shorted.
putting in LED makes said MODULE, think lights are dead.
(it measure current and goes, gee, lamp out)

so if you are not a tech or engineer, (learn that ) or skip all that. stuff.

How to wire aftermarket turn signals


The stock rear function ONLY as turn signals, while the fronts ALSO function as running lights (hence the extra wire).
On the aftermarkets, one wire will be the ground (usually BLACK).
The stock setup probably grounded through the metal casing.
The aftermarket housings MIGHT be plastic, so they need a separate ground wire.
Myself, I'd reverse them and wire the 3 wires to the rear, to have them act as extra brake lights also.

How do I install my intergrated tail light with turn signals i got the tail light to work but the stock turn signals have about three wires each


The stock turn signals have 3 wires1) Positive for turn signal2) Positive for cruising light (comes on with the light switch's 1st click)3) Ground.Obviously you can either replace the entire turn signal with the aftermarket one and stop using the cruising light or bypass the positive wire for the turn signal only, to the aftermarket one, and leave the original turn signal with the cruising light only.

I have a 1992 Buick La Sabre Custom. My brake lights are not working but taillights, turn signals and hazard lights do work. Switch ok. fuse ok. ????????


if your fuse is good. and you have power at the brake light switch and when you hit the brakes you have power coming out the otherside of brake light switch/which would be the white wire/ check that the white wire is sending power up the turn signal switch. if theres power there and your turnsignals work? im afraid that your turnsignal switch is bad rare but it has been known to happen.

Lights


The standard color codes used by most American car manufacturers in the older days were as follows: green - right turn signal, yellow - left turn signal, brown - tail lights. Of course, brake uses yellow and green. I'm not positive if it's the same on that particular car, but that is the standard.

Installing led 2 wire lights


I had the same problem with my 1997 marauder the only way i have found to make them work is to hook up the LED signal lights into the stock signal lights i know it sounds crazy but what i have figured out is that it uses the stock bulbs like a fuse. all you have to do is take the headlight out just like you did when you wired in the LED lights and wire in your stock bulbs along with the LED lights once you have done this put the stock bulbs in the headlight assembly and put the headlight back in this should fix your problem at least it worked for me let me know if it works for you as well good luck

06 cobalt stock system hook up


I cant really assist in this matter but I can let you know that I have a system in my 2006 Chevy Cobalt and that I have an aftermarket cd player installed. I had to pay $130 for a special adapter for it to be wired into the system because GM's newest idea of installing the stereo and airbags on the same wire scheme, is kind of a dumb idea.
