What causes electrical problems in a towed RV?

Any RV or towed vehicle vibrates in transit. And these vibrations will, at times, shake electrical connections loose, in addition to the wear and tear that wires and appliances go through in normal use.

What should I do if something goes wrong with my RV?

Because of these risks, the RV will have breakers or fuses to shut off power if anything goes wrong: a set of AC fuses or breakers to interrupt the 115-volt AC power coming from outside the RV if anything goes wrong in the 115-volt system.

How do you find a trailer light short?

Looks like Bassn is a faster typer! Well if brake and turn signal work then those wires ( green and yellow) seem ok and it would be the brown color common tail light wire that is bad. You can use a battery charger to check lights. Apply power to each individual lug on the connector and see what happens.

How big of a wire do I need for a trailer light?

This is just a standard 4 way connector with a ground, parking, and signal or brake lights. I believe there is about 25ft of wiring which should be plenty for a trailer of this size. They also provide the vehicle side connector too which I don’t need as the tow vehicle already has that installed.

What should I do if my trailer lights are not working?

Test all of the lights, from the backup lights to the turn signals and brake lights to ensure the problem is not the tow vehicle itself. If the vehicle’s lighting system functions as designed, grab a trailer wiring tester to check the tow vehicle socket. However, the tester must fit the tow vehicle socket.

Can a white Wire make a trailer go the ground?

That would make the white wire the ground. You can verify this by testing the wires using a circuit tester such as # 40376. Connect the trailer to the tow vehicle and have someone operate the light functions while you test the wires.
