I plan to recondition it..and one of my first priorities is adding a house battery. I noticed it has an alternator with an external regulator. I'm thinking of buying an isolator to charge 2 batteries. I've seen diagrams on how to fit an isolator, but was wondering if I come off the regulator, or directly off the large terminal of the alternator to the isolato-or from the regulator to the isolator? I need to know how to do this. Any info or web-sites that might be helpful? Also any info about reconditioning these would be a big help.
