There is NO power draw from the steps when retracted or extended. I am not aware of any Kwikee manual that states wiring the step to the COACH battery. That is NOT the correct way. You always wire to the CHASSIS battery. I KNOW some OEM's wire to the Coach battery, but that is not the correct/best way. The reason is simple and this used to be a problem with National Motorhomes that wired to the Coach battery. IF you have a malfunction or dead COACH batteries, and the step is extended, it will NOT retract when the engine is started and will be extended when driving down the road. Wiring to the Chassis battery eliminates this problem. If you can start the engine you have enough power to retract the steps. Doug
From the install manual
Kwikee recommends wiring the
step to the vehicle battery instead
of the house battery due to
potential interference from other
circuits.
