Ok, charged the Battery and hooked it back up - turned the Ign Sw til the dash lights came on, then I put a small screwdriver blade against the pulley and body and there was zero magnetic attraction

Hope I don't need to start the engine, but I can probably get my hand close enough to the pulley to test it with the engine running if I need to?

Does me not seeing a magnetic attraction mean my alt has no shorted diode or a
stator?

Thanks for the help.... When I am able to, I'll disconnect the B+ wire and will try that test if needed.
