Brian,
Try ohming the generator to see what you get. I posted awhile back the
readings I found on a good generator so folks would know what to look for.
If you have Guzziology I believe it's also in there. There should also be a
wire coming from you D- on the generator going to ground or back to the D-
on the regulator. D- sits a little forward of the D+ and DF posts. It's just
a screw into the casing.

Greg, thanks for taking the time on the reply. Also thanks for all of
the information on your site- I did check it out before and I used that
information to pick up a generic regulator that I put in today- and
still having the problem. I rechecked all of the connections. As to the
blue/black wire you mentioned- I just used that as a splice of the
white/black wire- it does not go back to the fuse block it. It does
connect the white/black wire to the spade connectors on the neutral
(green wire) and oil (grey wire) lights. I checked DF to DF and D+ to D+
and the relay connectors and all of the other regulator connections- but
I will go check again. The tach is not connected right now but that
white wire is the ground- I made sure it was grounded and still the
blown fuses/short at the generator light. I guess I am going tpo go buy
a bosch generator for $100 tomorrow so I can riule that out too- then I
am going to take it all completely apart again and wire it from scratch.

Hi Brian, I've been following along a bit on this thread and thought I would weigh in on a few things... If you do decide to get a new voltage regulator, either give Gordon and Rick a call or pick up a generic replacement at your local auto parts store. For details on what you need for your Bosch system, you may want to check my site: |

I have a tendency to agree with others in that it is most likely not your generator. It might be your voltage regulator, but I'm more suspect of the wiring. I would start by double checking all of your connections. The terminal marked "D+" on the generator should have a red wire going to your indicator light and a grey-red wire going to the "D+" terminal on the voltage regulator. There should be a white wire going from the "DF" terminal on the generator to the "DF" terminal on the voltage regulator. I went back and examined the photo of the back of your dash http://pg.photos.yahoo.com/ph/wfrwasher/detail?.dir=/f924&.dnm=784e.jp g&.src=ph As I look carefully at the two connectors on the left side of the photo (right side of the bike) they don't look quite right to me. Specifically, it looks as if the blue/black wire is connected directly to either the green wire or the grey wire via the spade connectors. If this is the case, then this is what is causing your blown fuse. I went out to the garage and took a look at my old wiring harness which still has the inidicator lights/sockets/connectors and the male spade connectors do not make direct contact...it is only through the bulb that they do that. Now, it may be that I just can't see the connectors well enough to verify that the wires are not directly connected to one another?. Who knows? If you need a close up of my connectors, please let me know and I'll post them. When it comes to the indicator lights, here is how they work (I think I'm just reiterating what Paul already wrote)... 1. Neutral light - the bulb grounds at the neutral switch and receives positive juice from the white/black wire from the fuse panel. 2. Oil pressure light - the bulb grounds at the oil pressure switch and receives positive juice from the white/black wire from the fuse panel. 3. Lights indicator - the bulb grounds through the dash and receives positive juice from the yellow/black wire from the fuse panel. 4. Generator light - this one is weird and I don't quite get it (mostly because I don't understand the generator system as well as I should), but, the bulb must ground through the red wire (connects to the "D+" terminal on the generator) and receive juice from the white/black wire from the fuse panel. Each of the white/black wires can simply be spliced into one another under the dash. There is no need to run individual wires to the fuse panel. You may also want to check to be sure that you have the tach wires connected properly...I just see a single white wire connected in the photo and I'm not sure what is at the other end, but it should be a ground (the original color was black, I believe). If I'm not mistaken, since the entire dash is rubber mounted on the little isolating blocks, the dash is only grounded through the wire from the screw on the tach to a bolt on the top of the triple tree. I'm not sure if this sheds any light for you or not, but best of luck. Regards, Greg Bender 1971 Ambassador 2000 Quota http://www.thisoldtractor.com/gtbender |
