HWH Not Powering Up

[Jay Mathew]

I am unable to get my HWH control to power up. The travel light is no longer green and when I push the HYD button the panel lights blink and it shows the batteries are low. I checked the fuse in the Accesorie Panel box and it is fine, all the fuses on the back of the metal control box under the dash are ok. Is there another panel somewhere in the coach with a "clear" panel that I have been reading about? I tried the hot lead in the pump compartment was able to jump the pump and get the nose to retract/extend but not able to get the system to power up? HELP.

Thanks.

Had same problem two days ago and found loose battery connections on the house battery terminals

Jay,
The control box for my 2002 was behind the dash, near the center floor on the firewall. It did not have the clear panel, like the newer ones. If no one with an older coach can help you, try here and look at the 600 or 610 series.

Jay,
I had the little battery light come on on mine while trying to extend the jacks. This was 3 years ago. I replaced the batteries and have not had that problem since. I did find that if I drove the coach several miles, it would charge the house battery and the HWH system would work, so long as I could level on the 1st attempt.

We had the same issue and it turned out to be a cracked pos battery cable terminal....HWH controls are fussy about gettint the full 12V they want...

Thanks for all your replies. I am about to throw the whole unit out. Last night I was able to jump the pump with the hot lead leading me to the conclusion that the lead from the battery to the pump was fine. I have replaced all the fuses, checked the ground and such. I was able to get the travel light to stay on as I had one jack not all the way up so I manually bled the pump and up it went. Seems the pumps are getting enough power but the system, control boxes are not responding. The ACC fuse is only 5 amps so not much of a draw there. HWH has been really slow about responding.

Would really be nice if anybody could find the wiring schematic from Western for these coachs as I have had to track down countless wires from previous owners recklessness and such. Any other ideas I am open.

Thanks Jay.

Jay,

You haven't said, have you checked the voltage at the batteries and to the HWH system?

Just something to check, we had a wire on the back of the control panel that was loose on a couple of occasions on our 99. It was connected to the 10? pin connector that connects to the back of the push button control panel. Be sure each wire is seated properly in the connector. Our control panel did not work at all with that loose wire.

Good luck.

Jay:

As Ed mentions, there have been many postings with your symptoms that were the result of the control panel (at dash) having a loose connection or strained wire bundle. I loosened my bundle by moving the strap holding it a bit. The problems can be intermittant or unchanging, depending on the looseness.

Take apart the two passenger side panels below the dash so you can see the drawer and related wiring as you move it in and out. You may just find a loose or pinched wire. From the sounds of it, the problem is likely a bad connection, likely there.

When you checked the fuses, did you check all the ones indicated in the HWH Owner's Manual. There are many fuses and in different locations:

Here's for three slides. http://www.hwh.com/ml13997.pdf
Here's for two slides. http://www.hwh.com/ml19754.pdf and http://www.hwh.com/ml16957.pdf (ignore the engine access door)

My control unit was center coach, under water tank, in first bay, behind a carpeted panel, next to the main tank drain valve.

Good luck, as frustrating as it is, it will be something insultingly simple.
