Noticed Smell Then Smoke - Ideas?

I plugged my TT into the shore power at the house for a few weeks prior to having a guest stay in it.

Test ran everything fine.

Day or two before occupancy I went in and noticed the converter and water heater circuits were tripped. I flipped them back on and was GTG.

Refilled one of the propane tanks the day of occupancy and everything was working.

Hours before occupancy I turned on lights, central fan, refrigerator, water heater and TV.

It ran like this for maybe 6 hours straight....

Flipped OFF the refrigerator hour prior to occupancy.

Hour or two later I smell something horrible. It was dark and I could not see it, but the Interstate Deep Cycle battery was shooting white smoke out like steam from a teapot. I disconnected the negative then positive and removed the battery.

TT was GTG off of shore power for the rest of the night.

What gives???? Put the trailer under about 1/3 appliance load for a few hours and the battery smokes out???

Ideas??

  • You need to check the output of the converter - I suspect it's either too high or the battery has shorted internally. Disconnect the battery, let it sit and hour or so and tell us what its voltage is.
