Swing low, sweet voltage

Okay, it’s true, you have to hold the last word for quite a bit to get it to match the tune, but its not bad really. We’ve been having trouble with the air conditioner today cycling on and off. The temperature was slowly rising throughout the day, so when it got to about 80 in the RV I went into diagnostic mode. Initially I thought it was a problem with the coils freezing up in the air conditioner, but then I decided to test the line voltage. I found that we’re getting 105 volts when the air conditioner is off, but when it cycles on the voltage drops to about 90 volts and after 30 seconds or so the compressor shuts off.

The temporary solution was to bring out our generator and use that to power the RV. here’s what the voltage looks like when we’re running of the generator, a near-perfect 120 volts:


In a little while I’ll try plugging the RV back into the garage. I’ve moved the extension cord that we’re using to power the RV from an outlying outlet in the garage to the outlets immediately adjacent to the breaker box where the wires come into the garage from the house. That wiring is 10 gauge, as is the extension cord, so we should be OK. I suspect the problem is with the wire that connects the outlying outlets to the breaker box of the garage.

We will see how it goes, but it’s always an adventure when you’re living in an RV in your driveway!
