It better not be my alternator I just had one die and this is a new one. its a 95amp alt in a 72 VW SB vert. This weekend Ill go over my sled harness connections and make sure they are all ok.

Dors the alternator have an internal voltage regulator or is it an external box (if so, was it checked/changed as well?)

If you have a volt meter (multimeter), check the voltage at the battery terminals at rest ( car has been off for a while, no nconsumers on;. voltage should be close to 12.6 V. With car rinning at somewhat aster than idle (say 2000rpm or so) you should see close to 14.4V shpuld definately be above 13.8 and below 14.7V Exact "ideal" voltage varies with battery temerature. colder -> higher voltage required to fully charge the battery. Shouldn't really dup very much as you turn on big consumer like headlights, rear defroster, fan,stereo , AC (if electricity driven and not direct belt drive)

You could attach the leads more permanently and run them inside, and glance at the meter as the empeg complains...
