Don't you just hate it when

I may be wrong and if I am these guys will straighten me out. I want to think that if the wires are reversed this could be a problem. My gray matter is kinda fuzzy any more so ?????????????????????????????????????????????????????????

Wires reversed?

If you reverse battery hot and ground YES. The alternator diodes would cause this very symptom

If you reverse the ammeter connections, all that happens is the needle action is reversed, IE shows "charge" when it should be showing "discharge."
