I cant see a battery reversing its polarity.
The battery is sponge lead acting as the cathode and lead dioxide acting as the anode. The flow from electrons to produce amps is always from anode to cathode then it needs recharging.
When recharging the process is reversed and the electrical current from the charger forces the sponge lead back and the lead dioxide back on to the respective plates for use again.
If it were possible to put the Pb on to the PbO2 plate (I don't' think it is) and the PbO2 on to the Pb plate, it certainly would not last long.

A negative ground battery installed in a positive ground system should simply not charge as far as I know. (My father does that all the time). Most systems on a older tractor don't seem to care which way the current is flowing to operate.

I don't' know if this is the truth but this is to my understanding. Somebody please feel free to correct me if I am wrong.
I don't know why you would be getting a positive reading on the batteries negative????

I am going to my fathers and mothers in an hour for Mothers Day and he has a Farmall with a positive ground. I will do a volt check.

Its surprising how turned around I can get when they change just 1 little thing like which way the current is going.
