new oem ignition switch/key set ordered from ECS tuning Ohio $87 shipped. thanks Laitch. Wondering what happens to the switch to do this.. ie is it electronic or mechanical? would it clean up?
So I've been studying the start service manual looking for clues as to why this headlight would stay on. What about the power shedding relay? Does the headlight run through that?
The reason the link for ignition switch disassembly was provided in my answer to your first post was to aid in cleaning up the switch. My answer was a guess at the cause and cleanup would be a relatively easy way and inexpensive way to rule out
that as the cause.
The load (power) shedding relay diverts current from the headlight during start up.
I believe that Inge is trying to determine exactly what is happening with your bike by describing symptoms and causes. The parking light—a small bulb in the headlight assembly—and the tail light are in the same circuit—they light together when their switch is activated. If the tail light is not lit and it is the headlight, not the parking light, that
is lit, then from his extensive experience, he is positing that fused relay contacts in a circuit are a more likely cause of the symptom.
Hunting the source of electrical dysfunction takes patience. You might need to lift the tank, open the relay box and compare what is in there with diagrams on the site to determine if that's where a failure is likely. Sometimes just knocking the relay with a screwdriver handle will free a stuck contact. If that happens,
that relay should be replaced. Otherwise, it will be more complicated.
Posting photos of what you encounter might help others identify a whacked assembly.
