First of all look at my number of posts to determine how much experience i have with this stuff....

I have found that disconnecting the motor from the hand crank allows me to manually crank the gear easier. From what I have read in trying to troubleshoot related stuff, (note that means not experienced), the battery should really power the jack motor and the slide motors. Reliance on shore power to do so is hard on the converter.
