The wiring diagram I have for my bike is different than what is shown here. In the diagram I have, the center lead [Lb] on the Op Fog Lamp connector is powered by the circuit that powers the right turn signal (after the turn signal relay; odd) and the Blue [Bu] lead comes from the Hi side of the headlight Hi-Lo switch, which definitely runs through the starter switch.Shown is the complete power loop back to the battery of the 3 pin accessory connector located in the headlight bucket and the starter switch is also circled. So explain in electrical terms how it is possible to connect something to that conector in the headlight bucket and have it affect the starter switch in any way or even how it could affect any of the wiring since that line is fused.
In this post alone a number of common posters mentioned their switch has burned up even with nothing extra connected to it. So when a switch burns up, how is it that you determined the fault is with the lightbar on the 3 pin connector unrelated to the start switch in any way and not just another switch getting burned up from normal use.
It's interesting to see two distinct wiring diagrams; what year was the manual you pulled this from printed? My manual was printed in 2002, yet I have a 2005 VTX. Maybe I need an updated manual!
I'll be verifying which wiring is actually on my bike with a voltmeter later today, as I want to get a relay on the headlight and get my light bar off of the headlight.
