Kwikee step in line fuse? UPDATE,repair completed

Well there is the culprit. The magnetic door switch had a broken wire on one side of the switch,that was why I had no ground to the step. It works fine now.

Thanks to all who chimed in with suggestions.

Yes, thanks Paul. Yesterday i tested my incoming wiring and have no ground on the brown wire, that is coming off a magnetic door switch from under the coach, anxious to get under there today to check that out.

i found the panel you speak of AND if you remove the cover there are two fuses coming off the solenoids mounted back there. That was interesting.

1. Go to the 4 wire quick connect at the step
2. Large Red wire should have 12 volts all the time. IF NOT, then trace to where that wire is indeed fused
3. White wire should have 12 volts all the time. IF NOT, find the inside ON/OFF step switch and make sure it is turned ON, IF NO 12 volt power if that switch is OFF or ON, trace back to find the blown fuse.
4. The YELLOW wire is ONLY HOT when the Engine is ON and is NOT NEEDED for standard step operation
5. The BROWN wire comes from the Step magnet or pin switch in the entry door frame. IF you have 12 volts on the White and RED, jump that brown wire to ground and release, if the steps do not function, then the Step magnetic/pin switch wiring has a problem.
6. Starting with this checklist will narrow down what to find and save time. Doug

PS. HOW did you check the various fuses you found?

OK, finally found the time to check the wiring( imagine that leaving in 3 days and found the time) anyway, there is power to the white and red wire at the connection coming from the coach. There is no ground coming through the brown wire. A troubleshooting guide said to check for 12 volts between the brown wire (coach side) and red wire (coach side) nope, nothing.

My suggestion is to follow Doug's quick check list first, it's a hugh time saver overall.

I have seen the step fuses in a variety of places, near the on off switch near the entry, in the jumble usually found under the dash cowling, in the area in front of the firewall and in house installed fuse panels that mimic or are exactly the same as the chassis mfg used. Page 9 of the #888 manual shows three fuses, they do get scattered around and are sometimes hooked up differently that the schematic shows. Finding them is sometimes a **** shoot.

In my limited experience, in order I have found failure most often in the motor and then in the magnetic door switch. I guess a blown fuse is not out of the question but I've not heard of even one, the controllers and ground connections are seldom the problem in my experience.

Do an advanced search of dougrainer posts and you'll find hundreds of posts very similar to the one he made in this thread. He is experienced.

To check fuses I use continuity between each exposed pin on the fuse, I do not remove and visually inspect each one.
Michael,
That may be the case with mine. I can get it to operate using jumper wires. On to another adventure then will check it out when I return.

When the Kwikee step on our Class C motorhome wouldn't extend, I was never able to find an inline fuse. In our case, the problem was the motor, which was easily fixed with a new motor. If I recall correctly, if you are able to get the step to retract and extend while going directly to the battery, the issue is with the control board.
