51 Champion How to Polarize Generator

[cbonner757]

Good morning. Got all my work done, generator is back on. My terminals are unmarked on my voltage regulator, so how do I polarize the generator correctly? Only the left-hand of the three terminals has "B" scratched next to it.

Also, is it necessary to re-polarize the generator every time the battery is removed, or only when the generator is disconnected? I've seen it described both ways - maybe both apply?

Photos of the regulator (system is still 6V, positive ground).

Not sure how photo posting will work with the new forum.

I hope that this can be read...it looks like your regulator is different from the Champion example that they depict...

Thanks, Scotty, I had that diagram from the shop manual, but eventually found a diagram in there of which terminal is which on the VR itself (which are not labeled on my VR). I'll give that a try using that. It
shows B to the left, F in the center, and A on the right. Thanks!

Gents, is it necessary to re-polarize when I take the battery out, or just when the generator wires are disconnected? I've seen it written both ways, and maybe it applies to both??

[Scotty Bob]

My interpretation is when the wires are disconnected from the generator...think about it...I can't remember anybody re-polarizing their generator after a battery change...the service manual seems to support this thought...

I have never, ever re-polarized a generator and at one point we had three vehicles sharing one battery! I think you only have to do this if someone hooks the battery up backwards. Run it and see what happens!

Thanks, guys, I eventually found a line drawing of the voltage regulator in the shop manual that showed which terminal is which, and used that. Works fine.
