Slide Out Problem With 2001 Rockwood
New to the forum, so this is my first post. I have a 2001 Rockwood 26 ft trailer with a small couch slide out. The trailer has been sitting up for about 2-1/2 years, and of course some things aren't all working correctly. The slide out mechanism is electric, but nothing happens when I push the out button -- no noise whatsoever. I was able to manually crank out the slide, but no where in the travel could I get the motor to run (either in or out). I opened up the panel underneath the couch to access the motor mechanism, and checked the inline fuse -- it was good. I also checked the switch both connected and disconnected. I had 12V on one set of the wires but not the other. The switch when unconnected did make on both in and out.
What should I try next to troubleshoot ? I did see limit switches for the in and out travel, but don't have a wiring diagram to look at. Any tips on which terminals to try to check for power ? There is also a black box that has four screw lugs. There is 12V power to the middle two lugs. How would one tell if the motor is still good ?
