I did a lot of posting at the end of this thread: Kwikee step breaking control linkage!
I figured it was time to start my own. I have tested all the wiring and the only one that is not working is the door jamb switch. I have 0 volts either way, door open or door closed. It should be 12 volts when the door is closed and 0 volts when the door is open. I pulled the door jamb switches and found no connection problems and the switch itself looks good. I presumed the switch on the door would just be a dummy switch to make the ground connection for the door jamb switch but that isn't the case. On the inside of the door the wiring from the switch runs to a control box, I think it is for the remote control door lock feature.
I also found that if I close the screen door the steps will retract. Open the screen door and the steps work fine. I find this quite odd as there are no wired connections on the screen door running to anything. With the screen door closed and the steps retracted if I close the main door the steps extend. What in the heck is going on here?
I also ran a new test on the motor and along with a shot of some oil on the steps joints it works fine. I am most certain that the voltage is supposed to come for the control unit for the door jamb switch but I am really baffled at how the steps retract via the screen door. Anyone shed some light on this for me?
I guess it is just time to pony up for a new module as I am thinking that is going to solve my problem.
