Okay, this is getting too complicated for me now. I'm not good with electrical stuff. Thanks for the additional comments though. With more research, I found out my house 12v panel is circuit breakers, not fuses...push to reset if they pop out. Maybe someone is familiar with these Winnebago panels. Seems like you have to unscrew the panel to get behind it to do anything with these breakers (other than reset). Even looking at the wiring diagrams I found online, I cannot figure out the connection to the alarm clock. Of course, I know nothing about wiring diagrams.
Anyway, this is a pretty insignificant problem in the great scheme of life.
