GS1100 lighting problem?

[ToddB3]

A friend of mine just bought a 82 1100 and installed a new rr and generator and once we fired it up all the lights will dim slightly when you blip the throttle, he also has a tempature gauge that will flick back and forth when you blip the throttle? We checked all of the electrical connections and made sure the battery ground was tight, any ideas will be appreciated. It doesnt affect the perfomance, the bike runs like a scalded dog its just bugging us.

Thanks

move the R&R ground wire to the ground on the battery.

remove the fuel tank and check the harness plug that goes up to the instruments and front lights, this is a common point for lighting problems.

Also check voltage at battery both at idle and above 3-4000 RPMs at teh battery. Do what Focus told you and while you are there, make a ground wire that goes from the R/R mounting screw/bolt to the neg battery cable.

Thats whats throwing me... We checked every electrical connection and when we installed the new RR we hooked the ground wire to the neg. post. The lights will slightly flicker right after start-up, when the bikes warmed they are steady. Were probably worried over nothing but wanted to make sure its not indicating a problem to come.

Thanks

My new Electrex regulator threw me for a loop when I measured 14.8VDC at 2500rpm and only 14VDC at 4500rpm. Looks like it's OVER regulating, but it's still within spec and I don't notice any lights dimming when I blip the throttle. I still have issues with a weak stator so won't know more until it's replaced.
