And I'm hoping a tech or somebody who has experience working on or with these will drop by and help.
In the meanwhile, what Model/Serial Number/Year is this system?
Do you have any documentation of Installation, Operation, Parts, Troubleshooting?
By the look of the pic of your controller:
1. Doesn't look like the current model on their website
2. Seems you can operate jacks individually or in pairs
So, does any particular single or pair of jacks cause the stoppage?
Raising the Camper? Lowering the Camper?
My Happijac's are Model 4150 -- they are about 11 years old.
When the problem occurs, the light on the front of the controller turns yellow immediately, when the coiled cable is plugged. No combination of jacks will work, up or down. Then when it does work, the light turns green, and any combination of jacks from the controller will work normally.
I have another post re battery problems, and I've since learned that the low battery voltage may be causing the jack problem. I usually run the jacks with the truck motor running or while on shore power, so the battery is being assisted by the charging system. There may be a problem here, too...
Thanks for your input...!
