Charging light came on recently and I knew the car still had the original alternator. So instead of testing (assume) I just installed a new (rebuilt) alternator. Same problem - light's still on. Also replaced voltage regulator with solid state unit - didn't fix.
With the alternator disconnected from the relay plate the light goes off. I have 12v at each of the 3 pins for the alternator connector at relay plate but nothing from the (new) cable from the alternator. Please don't tell me I have another bad alternator... but do I have a bad alternator? I'm stumped. Ground straps all look find. Thanks!
