Hey guys, last thing to do on my 67 bug to get it on the road is get it charging. Just wanted to run this by you guys and make sure I'm right. Big red wire to D+, small green wire to DF, and that ground screw to a chassis ground (or do I have to ground it to the voltage regulator? The damn generator screw is sitting right behind my carb. I'm not pulling the carb to do this, so can I just loosen the generator clamp, spin it until the ground is reachable, and then run the ground wire? Thanks guys.

1967 was before VW added dedicated ground wires across the system, which is why you don't have a wire in the harness from the generator housing to the ground screw on the regulator.

Now, the generator is SUPPOSED to sit with the terminals facing top right. The cooling of the generator is affected if you have it in there wrong.

Thanks for the info. So if there isn't a dedicated ground I assume it just grounds via the generator stand and consequently the engine block? If so I don't need to worry about that screw on the side. I'll try n get a picture of the screw if need be.

Yeah, the generator grounds by being strapped to the stand and the regulator via the mounting screws to the body. 1969 was the year they added ground wires throughout the system. They did feel a decicated wire from the generator to the regulator was needed or they wouldn't have added it. Still, it would be a bit of a PITA to run one yourself.

No need to take a picture, I already have one, lol. At least, of how a 67 generator its supposed to look:

So probably having my generator stand powder coated was a bad idea??

I checked for a ground with my test light. It shows the genny housing is grounded, maybe by the regulator on top?

Should I try to remove some paint near the genny strap on the stand?

If I had a powder coated generator stand, I'd remove it from the cradle portion, just to ensure good solid contact.

I'm guessing as a short term solution, I could run a ground wire from the strap to a grounded nut on the engine case.
