ammeters are analog, old style round gauges, the shunts are internal to the gauge. I forget the amp numbers on the gauge face.
I will have to look at what side is wired, they show positive charging
when the alternators are spinning. Meaning the needle leans to the right charge side, not the left discharge side.
I think if the power comes from one side needle moves one way, if the power comes from the other, neelde moves the other way?
Is that how those ammeter gauges work?
Since I dont draw any power thru the gauge from the batteries, they never will show a dischrge. If I drew power from the alternator
output wire, it should show a discharge, correct?
The wire feeding power to one of the main positive buss bars from the main large heavy duty battery buss bar is perhaps a 2 gauge wire which is bigger than the alternator output wires.
