2014 Cherokee Electrical Probelms

[ddomine529]

We just purchased this 2014 Travel Trailer. Our camping trips are usually dry camping, no electricity other than the generator. We started the 2000 generator to charge the battery and to turn the television on. Immediately upon plugging in the generator goes into overload. We have tried turning all the breakers off and leaving off the air conditioner and microwave. As soon as the plug is inserted in the generator...overload.

When you are plugged into regular electricity the furnace will not work, the air conditioner turns on and air flows from the ceiling. If you turn the circuit breaker for the air conditioner off, then the furnace will light and work.

Also, when pulling the trailer the battery should be charging. After pulling the trailer 5 hours, the battery is dead. You need to run the generator and plug a battery charger into it. Then the battery will charge.

Nothing in the trailer works with the generator.. overlaod evytime you plug it in.

What kind of generator is it? Is it new? Have you tried using the generator for other things other than the trailer? maybe plug a circular saw into it. Are you using a small adapter cord between genset and regular trailer cord?

Not sure about the a/c and furnance issue but there maybe a thermostat issue or interlock to prevent both from running at same time. What is the specific make and model of your TT?

Some trucks do not come with the 40A fuse installed in the fuse box for the battery connection to the trailer. Check your manual. Have you hooked it up with the tow vehicle running and check voltage on battery with a multimeter?

Wow too many odd things all at once. Simple one first - If you do not have a multimeter (voltmeter) go to Walmart - Radio Shack - and buy a cheap one. Check the voltage across your battery terminals. Plug into your tow vehicle, start the motor and recheck the voltage at the battery - it should go up - at least 13VDC. (Note a fully charged battery should show at least 12.7 volts if you are below 12 volts time to charge.)

Next test your generator - plug in a heat gun or hair dryer and see what happens - If it shows overload the problem is in the generator.

It makes no sense that the air conditioner runs and not the heater and the heater runs with air cond breaker off. These are not interconnected. Test more and repost.

Here's a maybe - if your battery is dead (or very low) the circuit boards in the heater and air cond will not have enough power to operate properly. Make sure you have a fully charged battery and try again. It is also possible that if your battery is completely dead your onboard charger is pulling enough power to overload your generator.
