Disconnect the battery ground strap. Swap VRs. Replace battery ground 
strap.

I strongly recommend that you NOT try to repolarize the generator. This is 
only necessary under VERY special circumstances and there is enough risk 
of doing something wrong and damaging something that I usually don't 
recommend it.

In 30 years I have come across only one generator which needed to be 
repolarized and that was in a Karmann Ghia that the owner had installed the 
battery backwards, which reversed the original polarization.

Most people don't realize that everytime their charging system comes alive 
the generator polarization is "refreshed" so there is NEVER a need to refresh 
it just as part of normal maintenance.
