Voltage Regulator Issues!!!!!!!
the 70 and below diagram has a chassis ground and the 63 diagram does not.
You need to be much more specific, this is confusing. If you are talking about the VR the change was 70/ later VS 69 and earlier. What "chassis ground" are you referring to? What diagram are you referring to?
put a wire from the battery(black) to the FLD and it seamed to bring the charge up from 12.25 to 12.98 at idle and when i slowly brought the idle up in jumped into the low 13's. Jake
If you jumper a wire from the battery to the alternator field terminal, this causes "full tilt" charge, and while is a way to test, you should NOT drive the car this way.
Please re-read post 6. With a jumper from battery to alternator field, you should be able to bring up engine RPM and show a charge on the ammeter. You should show an increase on a voltmeter connected to the battery. If the battery is not "too dead" this voltage should come up above 14V
IF that is what you did, it sounds like the alternator is actually OK
If this is the case, make sure the field wiring is OK. RE-read post 6. Jumper the field to battery by jumpering across the two VR wires. That is, disconnect the VR and connect the two together. This should duplicate "full field" as above, and should result in a charge.
If that is OK, replace the VR. The VR MUST be grounded. Since you seem to be having trouble, I would REALLY check that the VR is in fact grounded. Scrape and clean around the bolts and flange, and use star lock washers.
