Something wrong with your thermostat, but if you are using a electronic thermostat and have the indication of supply like light in your control then you can replace the miniature relay that triggers the cool mode of the unit. But no indication of supply try to check the fuse, then if not works you to replace new thermostat.

Generac 5500XL, model#09778-7 no output. Changed the power regulator board. No luck. Flashed the 120 plug with 12-30vdc from DC board. Nothing. Excited the brushes directly with DC board. Only got 2.36VDC...

Double check your brush istallation. positive side toward rotor bearing, if you put 12 vdc directly into brush pack and check with a meter at the 120 vac outlet and have low or no voltage, you may have no resistance in your rotor slip rings, excitor & main windings also need a resistance check. 12.6-16.7 ohms (rotor) 2.26-2.80 ohms (excitation) .26-.32/.28-.35 main or power windings. Note: unit running when appling 12 volts to brush pack. 2-5 second only, ( This test tells you the rotor & stotor are ok )

Air conditioner not working plugged in or on generator, heat not working either--nothing 2000 jayco designer

If you have AC hydro for sure to unit, perhaps a fuse in the 12 volt DC panel has blown, or in thermostat itself. Hear any clicking at AC unit when turned on? If not, check all your fuses in 12 volt DC panel. Check breaker didn't trip also on 120 VAC.

DeWalk DC500 wet/dry vaccum doesn't work

Vacuum works with the battery but does not work with 120 volt. Every time I plug it in it blows the internal fuse. I have replaced the fuse inside the vaccum several times and every time i plug it in it blows. What do you think it could be?

Are you certain the polarity of the connections to the TV are correct? If you connected them in reverse you may have damaged the TV. If there's a fuse in line check that too. BMW
