Electrons flow from negative to positive. So on a positive ground tractor you are saying the right side should be connected to the battery-through the starter switch, and the load charge wires attached to the left?

I have one gauge (Stewart Warner) with Positive marked on the left terminal (looking at the face) a generic gauge with no marks, and a generic gauge with opposite markings. I just test them with a load on the unit before hookup. Part of the issue is that back in the beginning of electricity scientists got crossed up with the polarity of electrons and discovered their error after systems were being built. Oh well. Jim
