Troubleshooting electrical

[Tron]

hey guys. my first time posting a topic on here so bear with my stupidity. THe other day i was out riding my shee with sum friends and noticed both my front lights stopped working. I think my tail light still is good but i don't have a clue where to start. Any pointers or tips would be appreciated. Thanx guys.

If the taillight still works that's a good thing, it means it's probably not the stator or about half the wiring heh. Start with the simple things, bulbs are cheap so check those and replace if they are blown (get an extra pair); they may just be old although both at once is kinda uncommon. If you put a new pair in and rev it up and they blow again you know that the voltage regulator is either shot, missing, or not connected, it's the small silver box under the seat. If they don't blow when you rev it up, that may be the only problem, run it that way and see if they last. If they don't come on at all with new bulbs, check the contacts where the bulb mounts, then start tracing wires to make sure the connectors are tight and the wires are intact (not cut, burnt, etc.). Check the switch too, take it apart and see if dirt or grunge or something is in there keeping the contacts from contacting. It's a pretty simple system so you only have to follow a few wires (black ground, yellow, green and blue for the positive side from the stator to the volt reg and then to the switch, switch to lights).

 

If the taillight is out also, check the wiring to the stator and then test the stator with an ohmmeter, it may be shot. Good luck.

If the tail light is out too, don't forget about the voltage regulator...........the blue wire leading to the silver box by the CDI may be unplugged. It happens, and will blow the bulbs if unplugged.

thanx guys for all the help. I'm gonna check it out tonight.
