charging system trouble
We need to see a photo of what you are talking about. What you say SOUNDS like a "normal" pre 1970 alternator with one grounded brush and one field connector. The problem is, with "modern" rebuilts sometimes you don't get "what you think."
Your original should look 'sort of' like the one on the left. This is actually an oddball alternator. Your original would NOT normally have the hole at 3 o'clock with a brush missing. Yours would normally have an insulated field connector pictured at 12 o'clock, and the GROUNDED brush at 9 o'clock as shown
The EARLY seventies that use the later VR would look like the one at left, that is, "round back" but would have TWO insulated brush (field) connectors like the "squareback" on the right. The squareback came out around 73? or so and is a superior design. You can use the 70 and later, whether round or square, on your old VR, by grounding one of the two field connectors
