Thanks for the replies. So then, I should be able to check for continuity between the case and the engine block and if it's there, I'm good?



No.. You want to use a heavy guage wire from that stud to the engine. All the factory cars and trucks had a ground wire. You alternator is mounted with rubber isolators thats why there was a HD wire on the car. I would ask for another correct alternator.




Yep that is dead on right. It needs the ground wire because of the rubber mounts on the alt. Most alt bolt right to the block but some such as this use rubber mounts and need the ground wire. You just have to ground the alt case. Ron
