itsonlypain Posted January 31 Share Posted January 31 I have A 1951 Chieftain with the 6 volt generator system, With some questionable wires linking the Generator to the voltage regulator. The field wire is smaller than the armature wire and was wondering what gauge wire to use for replacements to get fresh wiring in there. Link to comment Share on other sites More sharing options...
Bloo Posted January 31 Share Posted January 31 (edited) The field wire is just a control wire and is probably 16. I am guessing 10 for the armature (and for the other big wire going inside the passenger compartment. Those carry all the current. I don't have a 51 manual. Do you? If so, look on the wiring diagram. It might be a little difficult to decipher, but Pontiac usually included it and it is probably there.

itsonlypain Posted January 31 Author Share Posted January 31 This is straight from the Shop manual and I looked it over and can see any sizing information. 1 Link to comment Share on other sites More sharing options...
Bloo Posted January 31 Share Posted January 31 Well that wasn't very nice of them..... I'm going to update my guess on the big one to #10 and edit my post above. I think you would be fine with #10 and #16. Bigger is better but the field wont care. If you have bare spots you could eyeball it and compare to the holes in a wire stripper. I don't think it could be 8. It just doesn't look big enough. 1 1 Link to comment Share on other sites More sharing options...
