The website is down but Kwikee steps were on most Fleetwood products. Kwikee.com will forward to Powergearus.com. The site is currently having problems. They are now owned by Power gear. There is a trouble shooting guide on the site. You should have a series 32 step.
Biggest problem is the ground connection under the step area that attaches to the frame.
Next there is two fuses located in the battery control center. One is about a 5 amp for control, and one 25 amp for the motor circuit.
Next to the door there is a switch. When pushed on the top the red light should come on. This is an indicator that the switch is in the on position. If it doesn't come on, then there could be no power or the lamp is burnt out. Both of these issues have been on my rig.
