Last post mentioned the charging system not working. Local shop that rebuilt generator said it's likely a bad voltage regulator. They did confirm the generator works fine when we took it out for them to check it. So we arranged a consult with Rick Astley, an electrical engineer who has written a book about MG electrical systems. He was very helpful. We had been correctly polarizing the generator field windings for positive ground, but had done it without the engine running. At Rick's suggestion we tried it again while the engine was running, and how it starting charging! As Rick says, it needed an electrical Kick in the A**! No red light, ammeter goes to right towards positive current. Decided to stop by the shop that rebuilt the generator to tell them what fixed the issue - the owner was gone, so I shared the story with his technician of over 40 years experience.
