Got rid of the points VR and went with the new kind. Boy what a difference. No more drifting to the left of the ammeter 0. When I drained the battery driving home at night last week because the old points VR got stuck and would not let the alternator charge I decided to finally swap it out. Should have done it along time ago asI have been through several old style VR's and they never seemed to work correctly.
Still have yet to discover the fault in my system - car is at shop today for rear main seal, etc. - they will also have a look at the charging system.........
A very simple swap. I now think you should change to the solid state Well's or similar VR at the first sign of weird electrical problems. I don' mind points in the distrbutor so much, but everywhere else like in my relay switch next to the evaporator for fan speeds they stick. Currently my AC will only blow on high. I just need to swap that 15 buck part out also but just haven't gotten around to it. I never use that fan but I sure use the headlights and need a good VR. I literally rolled in my driveway last Friday night when the point VR was locking up and made it a 3rd of the way up the drive before the car died. I couldn't push it in the garage by myself since I have an incline so I got an extension cord and put the battery charger on it and went to bed. The next morning I got it started and drove it into the garage. Then went and bought a new VR.
Ditto to all above. Finally got my battery gauge working correctly with the Wells VR. Last year replaced the VR with a NAPA, had alternator re-built. At idle the gauge read 0 but driving read +20 until unless lights were turned on. Pretty sure the battery was weak so replaced it, same thing. Replaced the VR, first trip she held steady at +5. Attached the Battery Tender to insure a full charge, the gauge is rock solid at 0 now. A slight blip to - when turning on lights etc. On startup, the gauge shows +20 or more for a few seconds, after a few minutes it's solidly at 0.
