The deity obviously didn't want me to attend last weekend's show in Anniston in the GMC. Friday morning i fired it up. no charge. So, off to Advance, new alternator, put it on, fired her up, charge on both batteries. So I loaded the coach, hooked up the toad, fired her up, and the DigiPanel went into alarm. 18 volts, and both ammeters pinned on charge. Rats. At this point, I transferred stuff to the toad and off we went for a good weekend. Jeremy Knezek, wife, kids, and grandparents met me Saturday at the show. We had a fun day, everybody petted dogs, the kids were well behaved (!), and they learned a lot about the intricacies of dog shows. Jeremy's Dad and he and I repaired to the hotel after the show for Sevenses and a late afternoon of football and lies, and then had a delicious dinner at Top O The River in Anniston. Highly recommended, Dixielanders will remember the Top restaurant in Gadsden. There are about three more scattered around.

So, now the move is to figure why the alternator went to full excitation. I suspect the 100Ohm wire, which has been spliced. I'm minded to go get a 100Ohm wirewound resister and hook it in in place of the resistance wire. Someone mentioned a nichrome section in this wire, does anybody know if that's true? If it's just Sitz wire, a fixed resistor will work as well. If it's nichrome, the operation will be different, although depending what the wire is doing, it probably won't matter. (Nichrome acts as a ballast, the resistance will increase with temperature) About all it looks like would happen is the alternator will be a bit slower to come up to current with a fixed resistor... not a great problem.

Thoughts?
