Re: Evasive /7 Generator Light Problem

I have been using one of the OEM regulators for some time and been quite happy with it, but after trying a couple more variations with the other new parts and coming back to the same problem, I decided to try the old diode board again, mostly on the let's go back to the basics theory. With a 25 mile...

Re: Evasive /7 Generator Light Problem

I am waiting on parts at the moment but will be sure to give the wiring harness in the back of the headlight a shake when I get it going again. By eye, everything looks tight and clean there. In the schematics, I see possible ground wires but not how they are hooked up. Have people tried different t...

Re: Evasive /7 Generator Light Problem

The suggestions about the springs on the brushes were helpful, but the problem remains. One of the springs for the brushes was a full rotation looser than the other one and the ones on the old holder, but once I had corrected that and started up the bike, the generator light came on at full intensit...

Re: Evasive /7 Generator Light Problem

The brushes not being properly seated and the spring pressure not being right make sense to me for when the generator light is dimly lit, and I’ll take another look at them, but could they also be related to the erratic and increasingly prolonged shifts to the light being on at full intensity?

Re: Evasive /7 Generator Light Problem

Usually it takes a while for the light to start coming on, and initially, it stays on only very briefly. But after the last time I went through the possibilities and added a new flasher unit to get the turn indicators working again, the charging light came on almost immediately and stayed on for ext...

Evasive /7 Generator Light Problem

I have been chasing a problem with the generator light coming on periodically but with no apparent pattern or connection to immediate circumstances on a 1978 /7 R100 for over a year and a half and need some fresh ideas. During that time and one at a time, I have replaced the rotor, brushes holder, s...
