Slide out motor wiring.

[KCP]

I’m getting a wiring short between controller and slide motor. Looking for location of wiring going to back motor on my 2017 Quantum.

The wiring harnesses run up under the slide on each side. They can be difficult to trace as they can run through the floor and walls.

There is a wiring harness running from the Controller to each motor. The harness plugs into the motor, which has its own 6" harness coming out of it with a connector.

The first thing to do is to check the top of the slide motors. You will need to pull back the bulb seal on the inside at the top of the wall with the slide closed. Then you can check the wiring going into the top of the motor.

There are times the slide motor can move and either pinch a wire there or even knock off the encoder at the top of the motor. Either will cause an error code on the Controller. You should also make sure the harness is plugged into the motor and Controller securely.

If you can't see anything obvious, you can try getting a long spare wiring harness and plug one end into the motor with the error and then run it out a window and plug it into the Controller to see if the error clears. If the error clears, then you know it is the actual harness and not the motor (or Controller).

I actually carry a 35' spare harness for troubleshooting or to get a slide in if a harness goes bad on the road.

You can also swap the two motor harnesses at the Controller to see if the error follows the cable or it stays with a specific motor. That can help you narrow it down to the actual harness or a problem with a motor.

The wiring can be inside a bulb seal on the side of the slide inside the coach. That’s where it was on the Challenger. The build seal served as a wire chase.

My problem is the slide is out. It starts to come in then the back motor dies and throws the code.
It only comes in about an inch before it stops.
Can I get to the wiring with the slide out?

If the slide box trim is up against the wall and the bulb seal, you can't get to the motor or upper portion of the wiring harness.

You need to do the Electronic Manual Override. This should be the procedure but you need to make sure you Controller says C1 or C2 on it.

This will allow you to by pass the codes and retract the slide... assuming the motor is functional.

You may not have a short in the wire.
You may have a slide blockage and the controller doesn't know the difference between over current and a short.

What happens if you try to retract again from that point?

Try the Override procedure that Judge posted.

There is a metal support fixture the runs from the bottom of the slide to near its top slide on the vertical walls surrounding the side itself. This fixture contains the track's rollers, the drive shaft, drive gears, motor and the wiring. These fixtures are accessible when the slide is closed or partially open. LCI rec comes the slide be opened about 6 inches before working on any part of the fixture.

The wiring on my bedroom slide runs under the bed around to the raised carpeted section of beside the slide. There is a wire clip (Adel) screwed into the carpet holding the wire before it goes into the chase in the vertical metal fixture. The fixture chase keeps the wire from chaffing on the track and getting caught in the slide wall gap.
The living room slide controller is in the center left side basement compartments and the wiring goes up through a grove in the wall into the metal chase.
LCI offers the wiring cables in 10 ft, 14, ft and 20 ft lengths. I think Thor MC Plant 750 only uses the 20 ft cables to there is lots of extra cable to get caught on something.
