A website search on that part number indicates that it's a 12 volt AIRCRAFT unit, with a 35 amp setting on the current regulator. It would be set up the same way as a regulator for an Oldsmobile, Buick, or Cadillac with the heavy duty generator. Make a couple more posts so you have access to the private message function of this site, send me a PM with your email address, and I can send you copies of the service manual pages that will give you a basic procedure and some generic specifications for setting those air gaps.
