sorry Paul, I forgot you had a new wire harness.
has the generator been rebuilt? (maybe contacts/brushes are loose or weak,
causing voltage spikes/overvoltage...) I recently read the description of
how the regulator works by controlling the strength of the magnetic field in
the field coils (which controls voltage output, independent of RPM)
which battery are you using? maybe these tractor batteries draw too much
while recharging?

The only thing is, my wiring is all brand new with soldered and then crimped
connections . That and a brand spanking new regulator that went 1 week past
it's warranty. I think the warranty part was the whole problem. :)Nothing is
made to last anymore. At least I got some fun out of stripping things down
and cleaning stuff up.

Paul,
When I opened my regulator, it also had fused contacts (forget which one but
prolly the same). I think that the combination of old wires, crusty
connections (including
grounds) and overall age (it looked like mine was an orig. Bosch) made it
happen. Don't forget to polarize.

I opened up mine today and the contacts on the D+ side were fused together!
There was no way I was going to be able to sand paper those bad boys! There
was even an arc mark on the side of the cover. Does anyone here really
understand the workings of a regulator? I bought a new one anyway and
replaced it, that way I can always keep the old one as an emergency roadside
repair part. The B+ connections were a little loose, but doubt that had
anything to do with it. I also bought one of the MPEVR32SB ($13.99)
regulators that Greg has listed on his site, but for the life of me can't
figure out how to hook the generator to it. It only has a connection on one
side marked "FLD" and the other side is blank. Jason will check his this
weekend and give me an answer then.

Paul and Bob, My regulator was bad once, or so I thought. I went out and
bought a Ford Falcon regulator and when I was about to install it I thought
about opening up the old one and checking it out inside (or maybe I didn't
think this up maybe someone from this list told me). Anyway, turned out the
points needed a little shining up. Did that with 300 grit paper, put her
back in and she ran nice. Took the Falcom reg. back and saved a whole $7!

Bob,
I did my ground the same as you, straight to the battery negative post. I
checked my regulator against another old one and it gives the same readings.
I even pulled the cover off it and nothing was welded together. Bikes been
running fine for a year already.

Paul,
I posted a similar problem a few pages back. My light came on, new
regulator, and I could tap the regulator and it would go back off. Finally,
100+ miles, the light would not go back off. Took off the regulator cover
and the NO(normally open contacts on the dual contact coil had welded
closed). This is the same problem I found in the old regulator. Have you
taken the cover off the regulator yet? If not take a look, a new one may not
solve the problem. I just got a reply from another rider and he mentioned
his problem was a bad ground on the regulator. Mine is tied directly to my
negative battery post so that is not my problem, but maybe another bad wire
connection somewhere. I'm going to check my generator and clean all the
contacts and replace the wires going up to the gen and see what happens. Let
me know if you find a definite problem/fix for your generator. Good Luck.
Bob

| Ok folks, took a ride to the gas station last night and on the way back the generator light came on and won't go off. Put a meter on the battery and revved it up and no change in voltage. Hooked meter directly to the D+ & DF on my Bosch generator and revved it up and got 0 voltage. Is this right? If I check on the regulator from D+ to DF I get a short. Is this right? I pulled the generator apart and checked everything and the brushes are new and move freely. I measured across the D+ & DF and got 4.8ohms. This according to Guzziology indicated that my field coils are still fine. No reading would indicate burnt out field coils. I checked another generator I have and it read the same (not sure on condition or operatability of this unit). I will pick up another regulator tomorrow and compare its readings to the one I have installed. Any other suggestions? Paul 73 Eldo "Elvira" 74 Eldo "Daisy" undergoing a full police restoration |
