electrical help- short form

[Norm Keller]

If you short the city light wires, you will not blow the headlight fuse because this circuit is not supplied by the headlight fuse. The city light circuit is supplied by the Main fuse. If the Main fuse is blown, it will stop power to headlight, running lights, instruments, turn signals, horn, brake lights, starter relay, etc. Conclusion, the Main fuse and Main circuit supplied through the White wire are still active. I just double checked this by grounding the city light wire on my bike which took out the Main fuse only. Norm [Non-text portions of this message have been removed]

It will be dim at idle...with a little throttle (up to 2000 rpm) will brighten to normal..then up the rpm scale at about 2500 it will start to flicker and go very dim again. Any Ideas? Regulator? Alternator? Thanks!
