Polarization of system

[John M.]

I have conflicting information and am hoping someone on this tech forum can answer this question? It shouldn't be a big secret but it sure seems to be, and the internet isn't much help in my searching, nor is the NCRS archives. I would just like a clear simple answer to this question.

In a C1 1961/62 electrical system there is a 12 volt generator and 12 volt negative voltage regulator. The terminal posts on the regulator are marked BAT (battery), GEN (generator) and F (field). On replacement regulators I have also seen them marked BAT (battery), ARM (armature) and F (field). I assume that GEN & ARM mean the same thing. Which two terminal posts do you very briefly cross with a jumper wire and short tap tap to polarize the system? The BAT and GEN/ARM terminal posts? or the BAT and F terminal posts? I have seen this answer three ways; BAT and GEN posts, BAT and ARM posts, which I assume are the same, and BAT and F posts. Which is correct???

If you can locate copies, Delco-Remy Bulletins 1R-118 and 1R-119A will tell you everything you need to know. Briefly stated, After disconnecting and reconnecting generator regulator leads and before starting engine "Polarize the generator, momentary connect a jumper lead between the GEN and BAT terminals of the regulator. CAUTION: Do not connect jumper lead between BAT and F terminal, will cause badly burned contact points."

Pretty easy to find with a web search e.g. "Delco Remy 1R-119A" should get you there. Note that the original documents had color wire schematics (red & blue). Some web sources have black & white copies only - look for the color ones.
