Worked great. Thanks for all the advice. I'm certainly more knowledgeable now about how to check for faults. Dan

Don't have my notes here but I seem to remember that you are never supposed to disconnect the battery when the engine is running or it may inflict permanent damage to the alternator.

I thought about that and it certainly could have been that, but one of the things I noticed when I installed it initially was that it never showed the charging level above the battery charge level. I didn't think much of it at the time, as I didn't know any better. Dan
