I have been looking at my system and reading all of the good work Wes has done posting information on this site. I have a Auto Lite, Type 1, Class B, Grade 1 generator. I have a Delco-Remy Regulator. The bulletin says this rerulator must be used witha "Circuit B" generator.

Is this what I have?

The 28 volt 25 amp Delco & Auto-Lite regulators and generators are funtionally built to the same mil spec. You can mix and match either way. Both the Delco and Auto-Lite generators are "B" circuit generators. "B" means the field circuit is grounded internally in the generator. So yes you are good to go with what you have.
