[Farmall] Oliver Cletrac HG Question

[Jim Becker]

If you reverse the battery, you need to repolarize the generator.  If you 
don't know which way the battery was in previously, you should polarize the 
generator because you MAY be reversing the battery from the way it was 
before.  It never hurts anything to do it.  It usually isn't necessary to do 
it if you just disconnect the battery and reconnect it later the same way.

Polarizing the generator tells it which way it is grounded.  If you don't 
tell it, it will flip a coin.
