I disassembled the gas valve in house 4 and found it did not work when heat is called for. The thing is 10 years old or older. The regulator problem on the generator controller turned out to be a miswiring - went out to the greenhouse with Libbie and installed the generator controller and made a test run with it. All was well. Rewired the controller terminal box so that house 4 thermostat turns on house 3 heater and also removed the FanJet from the thermostat. I will restore this when we get house 4 heater running again. Late at night I won an eBay auction for a new gas valve from Vista, CA. My winning bid was $36.83 plus $14 shipping. There were 9 other bids. Ii talked to Arlene earlier this morning - Tess died yesterday. Funerl is Friday - i went in with Arlene and Vicki for flowers.
