Just bought my wife a 99 40' FDS at an auction for my wife. This thing drives great. We are currently going through it from front to back. Most everything seems to work but I have many questions. First and foremost we have no power to the jack control panel. We can not find the fuse box that goes to this. Do anyone have any Idea where we might find this?

Alpine owners manual is worthless but the HWH manual is very helpful. Just cant locate where on the coach is the fuse box for the controller.

HELP!

The fuses are on the control box which is behind the dash on the early coaches. Pull the panel away that is in front of the passenger seat and then remove the cover on the left that is over the fan unit. The control box is on the floor and you should be able to pull it out far enough to check the fuses.
Does the generator slide work? This uses the HWH hydraulic pump and solenoids but bypasses the control box so that may help to narrow the problem down. If the slide does not work there are other fuses inline with the pump in the small compartment behind the passenger front wheel.

Thanks so much for the quick response. We chased the wire and after removing the corner panel to the controller box. After burning a couple fuses we determined that The orange line that runs into the back of the controller that has a mid line connector shorts the fuse when it is connected. Also in order for the slide to open or close I have to use a jumper from the hot side of the Generator slide button. the red hot wire feeding the power switch for the slide is not hot.

Any thoughts?

The power to the red wire feeding the generator switch comes from the pump relay so it is possible the inline fuse in the HWH compartment has blown. Another confusing thing is that the power to the control box/panel comes from the house battery whereas the power to the pump comes from the chassis battery so make sure both are switched on. There is an accessory relay that is turned on when the ignition switch is in the auxiliary position and this feeds the HWH panel, radio and heater fan. Check you have power on the output side of this relay, I have had to replace mine as it would work intermittently. I have also had to replace the generator switch. I have not had control box issues so can't help much beyond what I have said. Hope this help somewhat.

Oops. I accidentally reversed which battery does what. The chassis battery provides power to the panel and the house battery provides power to the pump unit.

Thanks we will chase this down..
My propane tank Is full but I have no gas to the stove or refer. Is there a main valve or someting I should be turning on. Also there is a valve at the tank that has Vapor label over the top of it . Is this the main valve. When I turn it on it seams like it has a leak at the valve but I'm not sure.

The valve at the tank is the main valve. It may have a seal out of the handle that you turn to open it. Try opening it all the way until it stops. If hear or still smell propane then the regulator right next to that valve might be bad. You should hear and smell the propane at the stove with the main valve open and stove knob on. If not I would check the regulator. Be very careful if your not use to propane, it’s very dangerous. Let us know. Gator
