GSXS 1000F Headlight dimming

Hello, was wondering if anyone else rides enough in the dark to notice the headlight either on high or low dim considerably under any conditions? I can be riding top gear 60 mph and the will go very dark for about a second or two, then come back up. Sometimes when I am riding and just twist the throttle without shifting it will dim. Its like there is a load on the electrons often for no obvious reason.

Sounds like you need to have your stator (alternator) checked.

Itís certainly not normal. Alternator, regulator, battery or connector. Iíd get them all tested if itís not something you can do yourself

Def not normal. If you have the service manual it details how to check the charging system.

Assume you've done the obvious and checked for loose connections - battery etc.

I don't usually ride at night, but I have a voltmeter and do notice that it drops a few tenths of a volt when the cooling fan kicks on. But that's at idle...shouldn't drop much, if any at all due to that when at cruising rpm. Have you added any accessories that could be shorting or drawing high current? You may just have a bad/loose connection, either in a wiring harness connector, at the lamp itself, a battery terminal or ground lug. Also could be a wire shorting to the frame due to vibration rubbing through the insulation. I would try to figure this out before doing more riding as some of these scenarios could be dangerous.
