Two leveling jack will not go down

I hope this helps somebody..I fixed my jacks with a clamp... https://youtu.be/Qu5f2Iu4NRo

Oh BTW the database on this forum was hacked and passwords were stolen, just a heads up!

It all came down to grounds. The ground lug had 9 wires going to it. I cleaned them all up, replaced a few connectors and now all jacks and the rear slide work as expected.

OK so apparently the motor did fry. Took it to a local shop that rebuilds motors and thy said they could not get the parts it needed and sold me a new one for less than half of what HWH wanted. Installed it, switched the wiring to the middle relays and the LF worked and the RF did not so I assume I do not need to replace the relay and it’s electrical. Did not switch the rears yet because its so **** hot, was 105 out today. Phew!

Tried jumping it directly with a jumper cable to the lug on the motor, still nothing, not even a spark. Tapped on it with a hammer and still nothing. Going to take it to a shop that rebuilds electric motors here in town tomorrow. The crappy part is even once I get the motor fixed and I back to the issue of those two jacks not working.

You did not burn up the motor. IF it is fried, it is because it reached its long term operational limit. You can jump to 2 large terminals on the solenoid with a heavy gauge screwdriver. Bypassing the internal touchpad. IF the motor fails to run and you get heavy arcing, your motor is fried. It is held on with 2 screws. Remove and take to a local starter/alternator rebuild shop for them to rebuild it. Doug

Ya my brother said the same thing, I tried jumping the solenoid with a screwdriver and didn't see any arcing but I do see 12 volts with a meter. Thinking maybe a bad connection somewhere. Once it cools off a bit outside I am going to take my long jumper cables and try going from battery positive to the lug on the back of the motor, if it spins I will chase down the bad connection.

I talked to a tech at HWH today and he said they should open about 5-6 turns. So I opened them further and the jacks retracted. But now the motor is not working. I assume I ran it to long and fried it. I tested it at the terminals on the motor relays and I get 12.5 volts to it when someone hits the switch. So now I am in the hole even more that when I started.

Be safe, remove the wood block

Yes I am sure, I worked them open and closed a bit just to make sure they were open. I will crack the line on the front one at the jack and try to push it up again tomorrow, will let you know what happens.
