HWH system won't come on at times....

[Rich]

It is a Chevy Chassis on a '97 Rexhall, Class A. All fuses are fine. and I have not had to shut down the hydralics because it usually does come on for some reason....Is there an adjustment on the emergency brake switch, because I know where that is....The system is a joy stick early system...Just trying to avoid the headache of messing around with it....

You have guessed the usual issue but far as I know there is no adjustment unless the switch has completely fallen apart in which case it will not work period.

Is there an Emergency Brake indicator on the dash? Here is why I ask

On my Workhorse (Chey engine) the parking brake pedal switch has the jacks sensor wire hooked to it. The dash indicator is hooked to a tap off the jacks cable. SO if the dash indicator is ON.. then the Jack sensor lead MUST be grounded

You need to post on your original one.
