12v to ground on signal lights

Hi there,

I have the E fuse that burns as soon as I change it.
Signal light (left and right) + horn + brakes light no longer work. I have tested every mechanical command without succes. Does anybody had the same pb and could help me ?

Thanks to all of you.

Sounds like you're right, "12v to ground",i.e. a dead short. Although I haven't had this problem you can troubleshoot by disconnecting the battery (always disconnect the neg first, and reconnect it last). Then using a volt meter or continuity tester, follow each wire on this fused circuit and check each fused "hot" wire for continuity (a path) to ground. If the bulb lights then there is a path to ground somewhere on this wire between the fuse and the "load" (light bulb or horn or what-ever). If using a volt meter, set it to OHMS (resistance) and test for any amount of resistance. A good circuit should read infinite or O.L. (out of limit) resistance. A small or large reading indicates a short in this circuit. Remember that you are checking the "hot" wires (before the load) to ground (after the load.) Also it could possibly be shorted somewhere before the fuse(not likely) or across the load (a bad light bulb socket). Is the fuse blowing as soon as it is installed or do you have to complete the circuit first by making a switch (such as turn signals). If a switch has to be made, then which one? This can narrow it down. Hope this helps somehow and good luck.

 

Hi, thanks for the answer.

I have already checked every load and they are all ok, so I'm sure it's a circuit problem, the only question is "where ?" ;D

Fuse was blowing when using any load of the "E" fuse circuit but know it's blowing as soon as i turn the key on.

I'll find 8) and let you know. thanks again

 

Hey Laurent, I found a thread in the 98-01 model specific section discussing a short in the same circuit as yours. Same symptoms in 2 instances that led to a problem with the front brake switch or said switch wire rubbing the fork. Might be worth checking out.

 

I also had a problem that I did not see ...the wire to the rear bulb was just hanging on...check all wires.
Not that you didn’t...but I was surprised to find I missed one. Something so simple can cause so many problems.
The current would jump form the wire to the frame draining the battery.
