However, I have the genset running. In the end, nothing was wrong with the unit. The coil tested out fine, and while the ignition module failed the test described in the Service Manual, it passed a test suggested by Len K over on the SmokStak forum. I cleaned all terminals with a wire brush, hooked everything back up, and the genset runs like a clock.
One thing that is strange about my genset ignition control module is that most modules have only 2 leads, a red and black lead. The black lead goes to the negative post on the coil, and the red lead goes to the positive post on the coil.
But on mine, someone has, very professionally, spliced the red lead into 2 leads, and one has resistor and goes to the coil, and the other has a capacitor and goes to ground. The wires have actual printing on them "T1+" and "GND", so this does not appear to be a hack job, but some kind of commercial installation.
The folks on SmokStak say this is a "Pi Filter" for RF noise suppression. Onan does not think the splice should be there (from them), so my suspicion is that Winnebago made this modification to the unit to prevent RF interference with on-board electronics. I have an email in to Winnebago to find out. Not that it really matters at this point - the unit runs fine once again as it always has in this configuration.
