Ongoing fiddling continues. I've pulled each contact from the connector that connects the bell to the windings and flowed solder into the crimped connections. The ohmeter says I have zero resistance through the power windings. I have 3 ohms through the control winding with 1.3 ohms on each side to the center tap. I have zero ohms at the rotor winding.
I understand that I may have a short in a winding, but with all of the wraps there are in a winding wouldn't a short in a winding just make the voltage a bit low? Whatever it is takes my field voltage to half of normal. The problem appeared to be temperature related. I have done tests outdoors - below freezing. Today I have all of the coils indoors at 70°F. Maybe I'll put it all in the oven and take it to 100°F and check it again. It seems that something should change value but not fully fail.
