Re: cant get my 69 to charge
Yep, you'll 'full fielded' the alternator and it proved good and if an ammeter was in series with the BAT wire from the alt, it would have shown an indication close to the stamped amperage on the alt case, I hope.
Using a voltmeter, the charge voltage on BAT terminal would be, or should be, close to 0.2 volts, across the battery posts. An, there would be charge voltage on the brown wire as this wire goes to the other side of the GEN light, ignition on the other GEN bulb side, and light would be, or should be out.
A voltage lower than charge voltage would be on the field wire indicating the field being energized for alternator to change energy from mechanical to electrical, yada, yada. Also, placing a screwdriver on the rear bearing, you would feel a magnetic field, again, dependent upon the amount of current being drawn, more current, more mag field.
I would look to see with an ohmmeter if the VR chassis is on the same ground as the alternator case. Sixty-seven's and sixty-eight's have the VR mounted on rubber well nuts and a strap from the chassis to radiator support for the ground continuity; sixty-nine's, I believe are hard mounted to the rad support. Might put a star washer between the VR cahssis to rad support to make sure of ground. After 10-15 minutes of running, the VR cover or ambient area of the VR should be hot, 130°F or so.
You can always replace the mech VR with a wells unit, P/N VR 715, and transfer the cover for original look. Also need a tight belt and clean battery clamps & posts.
