Ok, dumb question, but I'll ask. I installed my motor on the shutter and hung the changer on the magnetic contacts. At first I though the battery might be too low for the charger to do it's thing, but then I measured the voltage across the contacts and found 12.7 volts. So there is a charge on it. I'm still in the install process, and was trying to manually run the motor to get a few inches of the track rolled into it so I could mount that on the dome. I do have the power connector plugged in too, but nothing happens when I push the rocker switch. I don't have any magnets or dome rotator installed yet (I had the familiar double side tape issue - another topic!), so not sure if I'm missing something that needs to be in place?
