Still battling slide issues

Iím still having trouble getting my slides to work on my 2015 Fourwinds class c. I accidentally crossed the positive and negative battery cables on my coach batteries. I have fixed everything accept for the slides donít work and I still need to replace the positive battery cable on the chassis battery.

The slide controllers are both getting power but there is not good power coming out. I have checked the 30amp slide motor fuse, all good there. I applied power to the slide motors and they work but there is not power coming out of the controllers. The switch on the wall by the bathroom for the bedroom slides does nothing and the button on the main control panel by the side door does nothing. I have tried pressing the button 6 times and holding the 7th to override and I do get all the lights to flash but no power to motors. I also get no error codes on either controller as well. Any other ideas? Iím thinking I might need to replace the controllers?

Did you check your 30A fuse with a continuity tester or just look at it? I recently had a failure in my leveling system and the yellow 30A fuse looked fine but was not. ĎBout drove me crazy trying to figure it out. If you donít have a multimeter try just switching the fuse for another. Unlikely but it worked for me.

Yes, it was tested with a multimeter and I switch it out anyway just to be sure, still not working.

Was hoping itíd be simple. Hope it doesnít turn out to be a fried controller. And Iíd have no idea how to confirm that! Best of luck.

If you press the extend switch twice in rapid succession, you reset the controller. Holding it down for the third time will send power to the slides motors and the lights on the controller will flash alternately if the slide is moving. If the slide does not move, then there will always be an error coded displayed if the computer part of the controller is operating normally. If you press the extend or retract button again while the error code is flashing you will reset the controller and erase the error code, The slide motors always draw power for the motor brake so there will be a 6 to 8 volt potential on the controller's output to the motors. There will never be an error code when the controller is in emergency override as all safety features are disabled.

Ugh, please disregard all. My dumb a missed a fuse. I’m back in business! Thanks to everyone who has helped. What a great forum to be a part of for my new (used) motor home.
