Turns out the problem isn't entirely fixed...I was only halfway to a solution yesterday.
If I try to start the generator, the power shuts off in the house just like it used to. The indicator light on the main power switch acts just like it used to...if I try to turn off the power, the light glows dimly.
But if I crank the engine, the main power switch operates normally. Once I turn on the main power switch again (i.e., off and back on after cranking the engine), I can now use the 12v system and start the generator.
Also, when the engine is not cranked and I try to start the generator, I can hear the clunk as the house power goes dead. It's probably the latching relay or a sticking solenoid, from what y'all have said. But at least it's usable for the time being...I just crank the engine and start over.
Regardless, I drop it off tomorrow for a warranty appointment for several other issues. :( I'll add this to the list and let them take care of it.
Thanks again to everyone for the suggestions...this helpfulness is what makes this place feel more like a community.
