Electrical issue slide out and stabilizers

[Ks8080]

Hey folks,

My family and I been RV’ing now 2 years and loving it.

I have an issue some of you maybe came across.

Slide Out and electric stabilizers seem to have no power but the tongue jack has power and batteries are full, I have 2 x 6V batt’s. 2020 Coleman Lantern.

There’s 2 DC circuit breakers on the A frame just by the propane tanks and I wonder if it could be these. They’re gonna be a super pain get out and check lol.

There’s a 40A inline blade fuse next to them also which I checked and all good, so I’m out of ideas.

Cheers in advance and have a great summer.

Different RV's have different wiring configurations. Post TT model for better advice.

Tongue jacks are often installed with their own fuses directly to the battery. So other fuses are likely the cause of the issue.

You are correct to suspect the fuses and circuit breakers near the battery. One small metal can circuit breaker may be the main battery protection circuit. They are often self resetting for safety during towing. Any others near the battery are suspect.

Measure voltage to frame from each side of the fuse or breaker. Both sides should have identical voltages. The voltage will be near 12 volts. Voltage from one side to the other should be zero.

If not there, then look in the main fuse panel in the TT. Mine has tiny red lights that light if a fuse blows. If yours does not have lights, then measure the same way as above.

Next look under the TT or under the slide out.

I wish you good luck and happy trails ahead!
