After getting my FA50 mechanically working fine, something else has to break, who knew?
After replacing my choke cable, I started to have electrical issues as describes:
-Rear light no longer stays on, BUT the rear brake light is fine
-Turn signals don't function
-Horn does not function
-Kill switch does not function
-Hi/Lo beam switch functions, but notifying light near the speedometer does not
All the problems disappear if the wheel is turned to the left, and surprisingly work better than ever better (Horn is much louder, lights are much brighter, etc) but if the wheel is to the right then the above occurs. However, sometimes it will either completely work, or not work, regardless of the wheels location. Another issue is that all of the above will work fine and the static rear light won't be on regardless.
Looking through this diagram for the FA50 the only logical solution is that there is a grounding issue or multiple positive/ground wire issues.
Any suggestions would be appreciate, while the other issues aren't required to be fixed it is a state law that I have an always on rear light.
