Kwikee 2 step system problem.

Thanks Kevin. I already tried opening them with the engine running and the coach and chassis batteries are both new. I've looked at the ground and it appears to be ok. We are on the road so I can't check the swing arm on the motor. (we are parked on gravel which makes it hard to do anything underneath the coach.) I'll check to see if kwikee still has the pdf on their web site. Thanks for your advice.
