New Alternator(B-stud?)

Does any know if that little bushing between the two connections on the B-stud is necessary?

There shouldn't be a bushing on the stud. There is an isolating bushing around the stud which is necessary.

I'm sure that this was just a minor oversight. ricksza is one of the most knowledgeable and respected members we've had, unfortunately he doesn't come around much anymore. If he did, he'd be a prime candidate for adviser status.
