Alternator ground cable - where does the other end go?

Aha! Thank you!

that it happens to be exactly where I connected it, but I wasn't sure that was the place that it's actually supposed to go. I really appreciate you taking a look for me. I did happen to take a look at the voltage drop end-to-end on most of these cables and noticed a while ago that I had about a half a volt drop on this ground. it kind of makes me wonder if I have a bad connection somewhere else or like a poor connection between the engine block and or head to somewhere inside.

It didn't occur to me until the ground cable came off the alternator that the blower motor should always be running if it's set to the defrost position. I have done load testing with and without loads and it did well, but I bet it will do better with an intact ground cable!

I am hoping to replace the terminals on the positive post with new ones in the near future. I know 13.6-14.1V is the usual healthy charging voltage for cars, but I always thought that these 740s ran towards the low end of that like around 13.2-13.6. Is that not true?

Cheers,
Will
