I think my slide motor is dead

[chiefward]

The slide will not come in or go out in my 2000 fleetwood Terry, model 275J. I have replaced the controller, in hopes that was the problem since the original one showed only 10 volts going to the motor even though over 13 volts was coming in to the controller. I removed the motor this morning and hooked it directly to the battery. Grounded the motor to the negative side of the battery and used a jumper wire to the red and black wires of the motor.(separately, not at same time) I get no movement whatsoever from the motor. I get 13 volts from the jumper wire and the motor housing. I did this test with the brake engaged and disengaged. Do y'all agree that my motor is shot? Any suggestion of further testing is appreciated.

P.S. The motor is a Power Gear 520576.

EUREKA!!!! I followed your test procedure and the motor is working. The problem appears to be a sagging floor at the rear of the slide that is binding and causing the motor to cut off. Will try and adjust the slide to alleviate this problem.

Thank you very much for the lesson.

STOP! (Please 🙂 )

This is a REVERSING POLARITY MOTOR. The polarity on the red and black wires + and - REVERSES with a switch. The metal body of the motor has no electrical connection to anything.

So connect your + and - jumpers to the red and black wire terminals and see what happens. Then reverse them. You should not see a heavy blue spark if the motor gear is disconnected from the load.

I got tired of screwing with the cheap switches OEM uses with slide outs, and now use a 100-amp Trombetta reversing solenoid. 30 amperes through a fast-on switch terminal is asking for a fire.
