Kwikee Step Problem

I have a series 32 Kwikee steps on an 02 Travel Supreme.

With no warning the steps do not retract. I ran all of the trouble shooting tests in the owners manual and the test show the controller bad, but when I jumped the motor direct from a 12V battery, it does not work either.

Has anybody had the problem that both the controller and the motor went bad at the same time with absolutely no problems before? I am scratching my head on this one, what do I replace first?

Thanks

check to be sure you have a good ground for ALL fuse locations, check to be sure you have good voltage (12.5v and higher )
Motors are available on the net for under $50 they are nothing more than a power window motor. The module is another issue

I should have added the ground was cleansed and checked and the power source I used for the test was my pickup pulled next to the MH with 12 GA wire connected directly to the battery. My MH is stored inside and plugged in. The MH battery tested 14 V. I am also taking another voltmeter up this morning and trying again.

I just found it strange that both the controller and the motor failed the test when I have never had any step problems, they just died the other day. Srange they would both go out at the same time? I was hopng someone else may have an answer of which one might be bad or is it possible they both died?

I checked the fused, but from your advice I will clean the contacts today.

Have you regularly lubed the steps? It only takes a single wet driving day then a few days of storage to freeze them up. If you are unsure, disconnect the motor arm from the steps. They should move freely in and out by hand. If not, I see lots of penetrating oil in your future

Fixed it. I took a fully charged 12V battery and placed right next to the step motor and jumped it with short wires. It took a couple of "bumps" with the positive wire and the steps started working. Apparently jumping the steps from my truck with a 10 foot section of wire allowed to much amperage loss.

What is strange, I ran the controller tests again and it still does not show power coming out of the controller to the step motor. But everything is working perfect. That one I'll never figure out.

My steps are lubed at least twice a year and everything is as clean as a whistle underneath. There must be a high spot starting on the motor armature.

Kwikee Step Motor Test procedure

Hi, I have spent many hours troubleshooting a similar problem. From your post, you said you applied 12 VDC to step motor with no result. Did you use the step motor chassis as ground and apply 12vdc alternately to both the yellow wire and red wires? In short, the red and yellow are both basically a positive lead to the motor. One operates the motor one direction, and the other wire reverses the direction.
I am posting some directions to test the motor, which is necessary before you purchase any other parts.
MOTOR TEST
When checking the motor, remove the two screws from the connector on the motor leads between the motor and the control unit. Remove the seal assembly exposing the Red and Yellow wire connections.
CAUTION: Make note of how the wires and assembly go together for later re-assembly.
Temporarily connect a 10 Gage wire to the Red wire on the 4 pin vehicle connector leave other end free.
Temporarily connect a second 10 Gage wire to the step ground cable and leave other end free.
1. TO EXTEND STEP: Connect the Ground jumper wire (fabricated above) to the YELLOW Motor lead. Momentarily touch the Power jumper wire from the Red wire (fabricated above) to the RED motor lead.
2. TO RETRACT STEP: Connect the Ground jumper wire (fabricated above) to the RED Motor lead. Momentarily touch the Power jumper wire from the Red wire (fabricated above) to the YELLOW motor lead.
If the motor does not move when power is applied in steps above but there is a small spark noticable, there may be damage to the motor windings. Motor replacement is required.

Silly question. When you was jumping from your truck, did you ground the 2 vehicles together? You may have a dead spot in your motor if it happens again.

I bad as I hate to admit this..I missed the first step when troubleshooting my step problem. Somebody ,prob, me, had shut off the on and off switch. Took me several troubleshooting steps before I checked the obvious.

Yes, I used the battery in my truck hooked up the same way I used the battery sitting next to the step motor except 10 feet of wire shorter. A SOLID 12V with full amps apparently did the trick.

developed the same problem since yesterday although the motor runs a bit up and stops, and when extending runs the steps about 2 inches and stops, its as though the gear inside slipped and now only allows about 1/2 inch of travel before the arm contacts the housing???

Since the steps stop either way due to the resistence of being fully extended and retracted, the first step is check they are lubed properly. It doesn't take much resistence to stop them with a little rust present.

If Turkey were attacked from the rear, do you suppose "Grease" would help?
