Neat little vacuum pump you built!

This style of alternator must not have a internally grounded case so it has a negative post on the rear. The 6 gauge wire is the one on the bottom in the first photo on yesterday's post. I did build that wire with a protective sleeve on it and that's why it appears larger than a 6 in the photo. It's tight quarters around the alternator bracket where it's routed.

Here's a photo of the rear of the alternator. I looped the ground wire down and around to the post on the head and attached it along with the negative battery cable.
