Chassis short to ground

[lpasekof]

Had an interesting experience today. As I was doing some basic maintenance got a jolt when I touched the chassis structure. Turns out is as about 114 volts worth of jolt. Took a volt meter to it and confirmed that I have 114 volts to the chassis.

I'm now going to start the process of figuring out from where the current is coming. I guess I'll start by tripping all my 110v breakers to see if I still get the leak. If so, I know the short is between the power cable and the breaker panel. If the current goes away I'll then start setting each breaker to see which one is the culprit. After that I'm guessing I pull out the magnifying glass and do the Sherlock Holmes thing.

Anyone else have any thoughts?

BTW this is on a 2003 Journey DL.

Your problem is going to lie within a neutral somewhere. With no netural present it will seek a ground instead. Were you runing the genset or did you have it plugged in? If plugged in then check your outlet (supply side, i.e. from garage, house) neutral to make sure it's really a neutral. Use your meter from either side to neutral and either side to ground, post the readings here.

Thanks for the suggestion. I've isolated the circuit which has the "leak". Fortunately, or not, it's the refrigerator. As soon as it switchs from propane to AC, the voltage spikes. I've noticed an issue with the fridge not cooling on this trip. Freezer is very cold, but the fridge compartment is not. The circuit board is buzzing a lot. I'm suspecting the circuit board may be bad but I don't think that accounts for the fridge compartment being warm. Likely time to take it in for service

For now, we're working on propane. Will stay that will til fixed.

It is likely you have 2 problems. The first is a bad refer heater element that is shorted to ground. The other problem is a bad ground connection. If your ground connection was good, it would either cause the breaker protecting the heater element to trip or at least carry the short to ground current so that there would be minimal chance of a shock to the earth. I'd check both...

That is not a short to ground, that is a combination of no safety ground and a short from HOT to Chassis ..

OR: a seriously mis-wired plug (White/green and very likely black transposed)

NOTE plug OR outlet. I'd get out the adapter and three light tester and plug that in instead of your RV
