Happijac Issue -- Intermittent

[Old_Islander]

We have Happijacs on our camper -- this past weekend, there were intermittent cut-outs when running the jacks up/down. This is the hand-held controller:



The yellow light would come on almost instantly (instead of green), when the coiled cable to the relay module was plugged in, and the jacks would not respond to the buttons. Then a few minutes later, the light would be green, and the jacks would work normally.

The remote has been babied and kept in a warm place in the winter, and in a zip lock bag when we're on the road.

Any advice on what to check out?

If the remote needs to be replace, does the module located inside a storage cupboard also need replacing?

Thanks for your help...!

You mentioned you may be having battery problems. Does the yellow light act the same when you are plugged in to shore power?

[Old_Islander]

Yes, I tried resetting many times, and the light instantly turned orange instead of green. When it was acting up, the green light was never on long enough to time out. Just instantly yellow upon plugging in the coiled lead from the relay module.

The controller times out by design. Just reset it the way NEOK explained above.

When you press the middle red and blue buttons at the same time the yellow light should go out and you should get a green light the way my control works.

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?

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...!

Hopefully you didn't get the remote wet at some point. I did on my Artic Fox back in the day...ended up having to purchase a new remote.

Following. I have a problem with my happijac too and I’ve looked all over for help. Even the manufacturer doesn’t return email.
