Is that right AC contact supposed to be measuring that low? And I have not inspected the battery wire yet. It disappears up under the engine cover and I'm not sure where it comes back out.

Sounds like I need to install a ground wire.

Thanks!

I hope your ground wire fixes it, but I’m doubtful.
That AC is kinda high. But we will see....
