Hook the battery up as normal to have ground on the frame and connect the red fuse lead wire to provide the hot side power to the buss bar on the BAT side of solenoids. Don't bother with the control switch yet.

Use a small clip lead or jumper wire to touch between the frame and the buss bar or small terminal on a solenoid. The motor should drive. Test the other solenoid the same way and again the motor should drive the other direction. If solenoids don't come in or motor doesn't drive the problem is ground to motor or a high resistance connection somewhere.

If those tests are good use the clip lead or jumper on the terminals on the other side of limit switch or at the control switch on the terminals either side of center. The motor should drive again. If it works on all of those the control switch needs to be examined to see what is happening. If the motor fails to drive at a point then the problem can be narrowed to what is between the go and fail.
