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!

If you did test #2 as you stated in the first post of yours I quoted, you are doing it wrong. No wonder you are getting goofy readings. Look at the picture in the link Roland posted. Forget the 5 paragraphs Coop posted. That's a lot of mumbo-jumbo to read. This is an incredibly easy test to perform.
One more thing.... if you disconnect the wire that goes from the R/R to the battery, (center wire) and just try to test the power coming from it, you will get nothing, or whatever nominal battery voltage is. That terminal won't put out anything unless it is connected to a load. See. Didn't take 5 paragraphs to explain that.
