Spent the afternoon with Gary Kosier trying to get his coach alternator to charge. He took it off, installed his spare, and took the removed one to AutoZone who said it's OK per their tester. Spare had tested good, but still no charge. 12V on both wires at the plug, nothing on the output post. This is a Cadillac engine, and a different alternator, having the regulator on the rear instead of in the case. Brush to brush measures around 3 Ohms, which seems about correct. We shined all the connectors on the relay post and the 12v source post, and replaced one questionable connection, but nothing. I suggested he coubnsel with Dollar Carb and Electric in Gainesville in the morning, and get a regulator and set of brushes which we can install. This cured mine which exhibited the same symptoms. Coach has an APC installed. My experience has been, some of the alternators simply don't work with the external sense line.
Meantimes, a lady is dead beside the road in Demorest, Tony Bennett just got there, called me, and said it looks like she had a dead battery. He's moving one of her house batteries over to see if that will heal the problem of no start and dead engine; and then will see if the alternator is charging. I'm waiting to hear back from him, I've a spare we can install if need be.
Gary can make it home on his Onan running in the daylight if need be. If we can get a hot battery in the lady's coach we can likely get it to his shop or my driveway or Frady's place in Buford if need be.
Keep watching this space, and remember - Ammeters are cheap.
