Intermittent Power Problem to Slides

[Schmill]

Have a 2003 3295RK that has been great until the slides decided to occasionally not work when the extend/retract switch pushed. The unit has been to the dealer (who found no problems) As soon as we got the unit back and went to the lake - no power to slides. We have checked all connections (all are tight)and the two black cables on the hydraulic motor look good. We have been able to get the slides to work by jiggling the black cables. Does anyone have any ideas?

Thanks a bunch for any thoughts.

Welcome to the Forum Schmill!

Hope this helps, as I'm assuming your 2003 is like our 2007. I had a 2003, but just can't remember what it had.

The solenoid is pretty simple - heavy cable + and - to the solenoid, then heavy cable ouptuts on the ends of the solenoid to each side of the motor. The small switch terminals are just 14gauge spade type connectors. When the switch is pressed to extend, it provides 12V to the switch terminal on the solenoid and latches the high amperage power to the motor to spin in the extend rotation. When the switch is pressed to the retract, it latches the high amperage power the opposite way to the motor.

It sounds to me like the reversing solenoid is going bad. Next time it stops, put a test light on the solenoid small terminals from the switch, have someone push the switch and see if you are getting voltage to the solenoid from the switch (verifies switch wiring - test both in and out). If you you do have voltage there, leave the switch depressed and check the large output terminal to the motor above the switch terminal. If no light, solenoid is bad. If it lights but the slides are not moving, the motor is bad.

Reversing solenoid is about $65. Be sure and get the 75A service rating.
