stock alternator burns brushes

This overcharging (over voltage) IS ALMOST ALWAYS due to either voltage drop in the harness or ground path voltage drop between regulator and battery. I've posted on this hundreds of times

In rare cases this is caused by the regulator, and also rare is a battery going bad

To test for harness/ ground voltage drop:

1....Turn the key to "run" with engine stopped. Hook your voltmeter as close as you can get to the bulkhead feedthrough the "ignition run." This connect to, amoung other things, the VR blue, the alternator blue, and the key side of the ballast resistor

hook your other probe to the POS battery post. You are hoping for a very low voltage, the lower the better. More than about .3V (3/10 of one volt) means you need to start looking

The functional path for the VR blue wire voltage is Battery........starter relay stud.........fuse link.......bulkhead connector.......ammeter (RED)........through the ammeter........out on BLACK........to the welded splice........branch off to IGNITION SWITCH connector.........through the switch.........back out the switch connector on blue "ignition run"......out the bulkhead through the firewall...........and to the under hood ignition loads.

ANY OF THOSE POINTS can and will cause drop

2...GROUND...........run this test with engine running at "low cruise" first with all loads off and again with lights, heater, etc running

Stab one probe directly into the mounting flange of the voltage regulator..........Stab the other into the battery NEG. Again you are looking for a very low voltage, zero is perfect, the lower the better.
Thanks for all your help , youre the one with the most insight on this subject(no offence to others,and I thank all too)but I found the answer in some other search ,link: overcharging the battery HELP

You are the one that proposed tests in that post and I followed your procedure and right after pulling the green wire at alt field connector I got my answer , bad alternator , so returning it tomorow and hoping I get a good one this time , again for everybodys sake never assume a new part is good , thanks for all your advice(I was really starting to wonder if I was testing all circuits properly)Thanks again to all and will post results soon!
