The Kill switch on my 88 LT250R does not work. What wires do I need to look at to try and figure out if my switch is bad or if the problem is something else. The bike runs great and I have just been using the key as the kill switch. Lights work fine as well.
Check your grounds or the internals of the kill switch could be shot.
I had a solder joint pop loose on a kill switch. Re-soldered and it was good to go.
Pop the switch open and take a look.
