You are both correct. I apologize. After some further searching, I came up with the following link, which is apparently the company who supplied the controls, etc. for the systems. Though the wiring shown in the schematic is somewhat different than my actual wiring, I believe I can correct the issue. I believe the problem does lies with the resistor, and believe I can order a new one through Lichenstein, Winnebago/parts dealer in Iowa. Here is the link to the manufacturer.
Evans Tempcon, Inc
I have also attached a picture, but it came out a little dark. Facing the front of the motor home, open the generator access hood, and look to the left on the firewall. The resistor is far left. (no wires going to mine in the picture since they are disconnected)
