Mertz Posted September 6 Author Report Posted September 6 Put on a NOS VR to match my generator, polarized it and I get the same readings. The side of the generator gets very hot pretty fast. I think I might need a generator rebuild. Can I get parts and do it myself. I already installed new brushes and a bearing. Quote
Sam Buchanan Posted September 6 Report Posted September 6 The most reliable and long-term trouble-free solution to your charging problem is here: https://www.ebay.com/str/HowardEnt?_trksid=p2047675.l2563 The installation in my '48 Plymouth is below. This eliminates the old genny and regulator and replaces it with a single-wire alternator. Quote
Mertz Posted September 6 Author Report Posted September 6 I would like to keep everything as original as I can. I can get an alternator that looks like a generator. Quote
Mertz Posted September 7 Author Report Posted September 7 I believe I have found the problem and it was mentioned very early in this thread. I found a very small spot in the wire between the two coils that was bare and probably caused a short. I covered it with cloth tape and that part of the problem should be resolved. Secondly I found the bushing was ovaled and the armature was rubbing against the metal plates causing the noise and possibly the heat. I checked the armature with an ohm meter and it is fine. Do I use the ohm meter to check the coils? I need a new bushing with the outside diameter of 0.69 and an inside around 0.55 which was the measurement at the narrowest part of the bushing but it needs to be slightly smaller. Are all autolite generators using the same bushing? Quote
Dave72dt Posted September 7 Report Posted September 7 Measure the armature where the bushing fits and the end cap bore. Those will be your guide to bushing size if you don't have a part number. Quote
Mertz Posted September 13 Author Report Posted September 13 I just finished installing the bushing and the armature slipped right in. I thought it would have been a tighter fit. It is all put together and seems to be spinning fine. I did a few continuity tests and in shows continuity between A and F terminals, continuity A to case and continuity F to case. Is that correct?

Mertz Posted September 14 Author Report Posted September 14 The generator is in and working just fine. It no longer gets hot and is charging nicely however it still sends the volt meter crazy. There must be a field set up somewhere that is causing the problem. 1 Quote
