Electric steps - HELP PLEASE?
I own a 2011 Newmar Bay Star class A. I have been fighting with my electric Lippert Coach Steps. I have followed the troubleshooting instructions from Lippert for the coach wire harness. RED always HOT, BROWN grounded with door open & open circuit with door closed, YELLOW is HOT with ignition ON only, & WHITE is HOT with the step power switch ON only.
I believe my LIPPERT control module is working. I unplugged the step motor & tested the 2 wire harness from the control module. I turned the step power switch ON & using a volt meter on the 2 wires from the control module. I get 12V when I open the door and -12V when I close the door.
I removed the motor and tested it on a separate 12V battery. It spins one direction and when I reversed polarity, it spins in the opposite direction.
My dilemma: with it all connected, I open the door and the steps fully extend, but the motor seems to be not dropping the current & the wires are quickly getting VERY HOT. Nothing happens when I close the door. What tells the control module to stop sending voltage when the steps are fully extended? Is the motor supposed to drop the current when it detects fully extended position and fully retracted position?
I tried bypassing the control module, with the motor installed. When I apply 12V the steps fully extend, but the motor keeps pulling current and the jumper wires get VERY HOT. Same thing happens when I reversed polarity.
Do I just need to replace the step motor, or is the control module supposed to drop the current?
Thanks for any help, suggestions, support, or input!
