Wiring Problem

When I posted that, I was referring to the ammeter because when I get 14 or a little more at the battery the ammeter shows a strong charge. When I switch regulators and get in the low 13's at the battery the ammeter reads closer to "normal" ( one line to the charge side). I really don't want to pull the cluster and swap the ammeter only to find it's not the problem. I find it interesting that each regulator gives me different results. All that being said, you did give me something to think about. I'll see about rounding up another volt/ohm meter and recheck the voltage running and not running at the battery. I'm using a $40 Craftsmen digital. Thank You!
