Tail light brake light turn signals dont work but headlight does my igniton switch unplugged could this be why?

SOURCE: My signal lights, hazard lights, and tail light aren't working.

Check the rear bulbs.If they are working (brakes+lights) check the wires.For the turn signals, override the flasher relay.If they are coming on then you need to replace the relay.If not then check the left hand side clip on switch.

There seems to be some short in the circuit of the high beam, you will have to follow the high beam wiring, best would be to get the color of the high beam wire frm the head light bulb socket and trace it along you will sure find somwhere the along it the short.
Check the light switch and the blinker switch too.
Hope this helps!

SOURCE: Rear tail lights and running lights not working.

Make sure that the rear light fuse is not blown
If not trace the brown wire from the rear lights & check for continuity between lamp holder & fuse
As its both rear lights & front sidelights it will not be an earth fault

Hope this helps (if so please mark as very helpful)

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.

To begin with, there is no relay for the brake light. That thing you hear clicking is a circuit breaker. You probably have a short circuit between the rear brake light switch underneath the bike and the brake light itself. If the tail lights work, then you know what circuit is ok.

Look at your rear brake master cylinder. Find the metal line coming out of it going to the rear of the bike. In that line, under the bike, you'll find a pressure switch. This is the rear brake light switch. The front brake light switch is located in the right side handlebar switch housing. If neither switch works the brake light, odds are you have a short circuit in the wiring from the rear brake light switch to the rear brake light itself.

Good Luck
