Archer use the same procedure as on relay. Red vom prob to one leg of switch and black to a good ground.
Never feel stupid Archer. Sorry but our computer went out and had to buy a new one. Glad you got it fixed. Not unusual for motors to do that after sitting. Now you know how to get to motor so you are doing great. A light tap on a motor is a mechanics best fix LOL. Hey, I have been a camper for just about half a century well guess I have since we started in 60s LOL. Last camping trip I had no electricity when hooked up. Have the energy management system so suspected the worse. Took the power 50 amp male end off and it was ok. Took cover of switch over system and it was ok. Went inside and checked power to main supply ok so dang what to do. Started checking all fuse and no volts to bathroom and like a hammer it hit me. Went in the bathroom pushed the Gfi and bingo power so never should you feel stupid It happens LOLWell, talk about feeling absolutely stupid. Got to the motor like I said. cut the red connection and tried to connect the VOM lead and ground it with Linda pushing the toggle and got no reading. Did tap on side of motor a few times while under the trailer and decided to wait until you responded. Low and behold, came inside, pushed the toggle switch and slide started to come in, so stopped and put it back out (only moved a couple inches), but motor sounded strong. Must have been an issue inside the motor like you originally said to tap on it. At this point, I am not going to try and bring it all the way in. Will wait until the day I leave and then see if it will come in. If not, will crank it in. Sorry for all the confusion. Your still great as an advisor and FRIEND.
