One more item re the generator. I want to know when it is running. A little Rf remote system seemed the way to go, but I had to sense when the unit was running. Since it is an emergency unit, I did not want to tap its electrical system, for fear a short would would mess it up, or might affect the warranty.
My solution was to mount a reed switch near the alternator which controls power for a battery powered pic controlled transmitter. The receiver is in the house, mounted in a hollow book I got at a hobby store. It works great so far.
