I think I need one of these. Somebody sold me one and I put a test light on the d+ terminal and battery and get nada like my others? Can't excite it to charge so not sure of its status. Unless replacing the voltage regulator/brushes could somehow bring it back to life?

Old wives tail, only works 85% of the time.
seriously, go to the Junkyard/heap and bag 3 brush sets, you'll probably win.

You are doing this testing while it's mounted in the car?
Really pretty vague about what you're doing and how.
Sounds like you don't even have a way to connect an exciter wire to it?

sorry, i daily drive a 79 rabbit. i swapped the mk2 diesel alternator into it last week and ran the battery down a couple times before thinking maybe its not charging :)
if i hook a test light between d+ terminal and battery + i get nothing with this alternator?
but if i slap some others i have in the garage back on the car the test light goes off.
unless i read wrong, i thought that was a way to test and mimic the chasis wiring(which i did because the red light didn't come on at all)

I'm with 745... I grab those regulators whenever I can. They are the most likely component in the charging system to fail.
