I have a 2008 Discovery 40x coach. As i read your concerns, it brings back nightmares.
Took it in to RV repair shop and they could not figure it out.
Took MH back to campsite and started to resolve problems.
Get all info on the system.
Let me help you find the problem.
I have not had a problem in 4 years.
It was a poor connection at the battery control location. Located on the roof of a compartment on the drivers side.
It has the control wires for the 4 jacks. The module is labeled for each jack.
- power is there on a bolt
+ power is there on a bolt
Look at each 4 wire connection where it connects to the mother board. Look to make sure that the brass wire connection (4 wire connector) is not being pushed down when trying to plug in 4 wire port to motherboard.
This system works the same everytime you push the auto level button. I think it is the front right( drivers side)
If any one of these jacks go into error, the light will show you which jack is in trouble. Make note of which jack.
The system will go into alarm. Once it is in alarm, you can do a reset.
DO NOT PUSH AUTO RETRACT IF ALL JACKS ARE NOT DOWN !!!!!!!!
Now we have the easy part. Find the control panel( where all the jack are wired to)
Make a cheater cord ( 3 ft in length 2 conductor) with alligator clamps on one end, large enough to clip onto the + terminal and the - terminal. Check to make sure that all connections for the 4 jacks are solid and plugging them in does not push out the pin. Must be solid connection.
With the cheater cor attached to the battery supply, push the other end into to the connector.
Which wires, the two larges one. Should be a red and black.
Do the front left and jack will go down or up. Reverse the wires on the plug and it will reverse direction. Lower each jack in the order above. Must be down 8 to 10 inches. Move it up and down, leave down and proceed to next jack. Look for bad connection on plug. Remember the light for the jack in error mode Mine was a not so good connection on the jack plug when it connects to the control panel.
Mine would work, next time not work.
My cheater cable is still in that compartment waiting for the next time.
