Is there any way to by pass the switch on the Ford park brake pedal, provided that I can find the switch. I would like to splice the wires that the HWH system is looking for and let it operate separately from the park brake?

When problems occur with the HWH system and it has to do with the right front jack, it isn't the jack itself. For some reason, that's the jack that is the last to get fluid or have the air bled off.
I'd check the solenoid like Brett suggested. He knows this stuff frontwards and backwards. Check to see if the handle is partially turned in. It has to be all the way out.
Due to the age of your coach, I'd change the fluid. It uses MD3, or the old style GM transmission fluid. It takes about a gallon. Syphon out the old fluid, pour the new stuff in and recycle the jacks several times.
Finally, lubricate the shinny part of the jack with the same MD3, using a rag or paper towel. I spray my jacks with silicone spray and have been doing that for over 10 years. They retract and store in about 5 seconds, and work great. I understand you should not use WD40 for some reason.
My springs are all still original and the jacks are all still original. I haven't replaced anything except the fluid. The coach is 20 years old.
When I had a problem with my right front jack, HWH said to send it to them for rebuilding. I didn't. They didn't have any other suggestions. Others on this forum suggested lubricating the jack and that's what I did. I changed fluid as a preventive measure and since it so easy and cheap.
Do you have kick down jacks? The reason I ask is simple. There is NO WAY 4 jacks can retract in 5 seconds. There is NO way 1 jack can retract in 5 seconds. But, if you have kick down jacks, yes the jack can kick up in 5 seconds but then it still has to fully retract the cylinder. Changing fluid will not change any aspect of the jacks. Doug
Yes, I have kick down jacks. And, yes, they store in something like 5 seconds. I can hear them when they \"park\" up after retracting and my lights go out. I confirm they are up by physically checking. I don't know why my jacks should be so much faster than other owner's jacks, but I can only assume it has to do with the amount (quite a bit) of silicone spray I've used over the years. I don't think the return lines are larger or the springs are stronger. I don't have any other logical explanation.
