Problems with Rear Slide

(1/2) > >>

Jack Whitmill:
The rear slide on our '04 36' Monterey has started to act up.  This slide is driven by an electric motor (not hydraulic).  We have found that the house batteries have to be at peak charge to operate the mechanism.  We have found that if the system fails we can either connect to power or start the generator and all is fine.
The system is basic but I am not sure how to trouble shoot.  We have the electric motor, a brake on the motor, and a heavy duty 6 lead rocker switch.  All connections at the motor and switch are tight and clean and I have 18 month old Interstate house batteries which I removed, cleaned, tested, and reinstalled.
This is a new problem and has not given us trouble in the past.
Any ideas?

Gerald Farris:
 The most likely problem with your slide, from your description is an out of adjustment brake. It can also be a motor on it's last leg or a binding in the slide mechanism so the motor requires max voltage (12.7 to 13.6) to operate.

Richard And Babs Ames:
Be sure you do not have a dirty or loose  connection somewhere including the switch then check to amperage draw of the motor.

Ron Johnson:
The only issue I have had with my bedroom slide is right after I leaned a ladder against it and basically pushed it in a bit. The fuse blew when I tried to retract it. I replaced it and all was well. I wonder if Gerald's suggestion of slide adjustment would apply here?

George Harwell:
Jack, I have an 03 Monterey that has displayed similar behavior over the years. Usually between 12 and 18 months the room will not move when the switch is activated. Each time I remove the switch and clean the blades with a small file or sandpaper. After that it works fine. I don't remember if it was only on battery power but will know to check with external power if it happens again. Being that it works ok with shore power I would think the brake is working normally. The symptoms indicate a bad connection or ground and can be very difficult to isolate. Does temperature change affect it? You may start with cleaning the house battery ground to the chassis.
