Landing Gear Motor works out, but not when in place

I ordered a new motor from Vanguard Mfg. I talked to a very helpful person in Customer Sevice by the name of Pam. She took my order and then sent me a page of advice and 14 PDF's on maintenance, installation and conversion to a two motor system. I'm impressed.

I'm tempted to go with the two motor setup. My toy hauler is nose heavy and it would help that puny single motor.

BTW I can unbolt the motor from the gearbox and it works perfectly. I talked to a few local RV shops and they all said the same thing as donn0128, bad motor. It is 7 years old so maybe it's time.

You may want to check your switch. I had one that corroded and one wire fell off the switch.

good electrical connections? including ground?

bad motor they are pretty cheap so order a new one direct from the landing gear mfg

I can hand crank the gear up and down. I'm plugged into shore power. I can hook my volt meter all along the cable to the switch, and back to the motor. It's 13 volts at each point I check.

What comes to mind here is:
Is there sufficient battery power?
Is the gear box running free...can you move it by hand?
Is there a binding in the shaft gears or teeth missing?
