Hi everyone, it's been awhile.

I have a new to me trailer and have run into a problem:

The bedroom slide will not move on 12v power. It just clicks. The kitchen slide works fine on 12v so I don't suspect the battery but it's possible.

The bedroom slide works fine on 120v so I assume the motor and gearbox are fine. It should be noted I have yet to even find the motor and gearbox. The slide has arms, not cables so I suspect the drivetrain is under the slide but it's an enclosed underbelly that I don't want to start cutting into just yet.

Any ideas?

Low battery voltage. If it works when plugged in the converter is putting out 12 volts to operate your motor. Check wire to battery and clean if bad.

Try looking under the bed, some will have a false bottom covering the motor

All systems on the trailer are 12 volt. Since it operates when plugged in, it will be a battery issue. Have your battery tested, if over 3 years old, replace it.

Check the circuit breakers on the trailer tongue. If they are weathered and have any corrosion on them replace all of them. Not hard to do.

I agree. Try using a different battery (even your truck battery).

I'll probably replace the trailer batteries this weekend, but I thought it was odd the front slide would work on battery (I'm guessing voltage drop to the rear slide due to length) while the rear slide wouldn't.

Also, the rear slide won't operate with the truck plugged in and running. I'm guessing it's just that sensitive?

Lots of variations in slide operating mechanisms but most with "arms" use either a motor turning a shaft with pinion gears that push the slide out or a linear actuator with motor and gearbox mounted underneath. Usually a "Through Frame" design.

I had a similar problem with my slide where it operated sometimes, sometimes stopped after a few moments of movement, and sometimes resumed operation after some time passed. I finally got frustrated with having to crank in/out manually.

I removed motor (which on my TT was mounted inside the frame on the opposite side as the slide and enclosed by belly cover). I removed motor from gearbox and dissassembled it. Found one brush was sticking in the brush holder. Wasn't making solid contact with the commutator and after a short period of operation the normal vibration in the motor would push the brush back just enough that it wouldn't carry any current into the motor. I had to spread the slotted opening in the brush holder enough to allow the brush to FREELY move in it and after reassembling the motor has worked flawlessly since.

Don't know what your system uses but when motors stop working on purely battery power, but work OK when the voltage is increased by connecting to shore power, it's almost a certainty it's voltage or poor connection related.

Before spending any money or extra effort on the issue I'd recommend connecting a voltmeter to the motor input and see if full voltage is reaching the motor when slide switch is engaged.

FWIW, most manufacturers recommend that slides be operated with shore power connected (or generator connected and running). Depending on the brand a slide can draw from <10 amp to close to 30 amp.

None of your slides are 120V. They are 12V over hydraulic or 12 Volt/mechanical. Some slides require more current to operate than others. Some manufacturers say to either be plugged in or have your generator running before operating sides and jacks.

So this is an ongoing problem. Sometimes the slide works, sometimes it doesn't. I have verified full voltage at the motor.

When it get stuck in the "in" position, I can turn the nut on the shaft a few times with a wrench to get it to move under electrical power again.

I'm open to any suggestions.
