HWH 210 Jack Brake interlock switch

elp70 · 03-14-2009, 02:49 PM

I have a question: On my 1999 Jayco Class C, (HWH210 with joystick installed)where would the parking brake interlock switch be located; inside the cab or under the chassis? In either case, where would I most likely look, to find it? The switch works intermittantly which I suspect is from corrosion due to my location on the coast of Oregon. Thanks for your help.....elp70

I posted this problem down in the Class C section - but, rec'd no responses. I know that someone on this site has had HWH hyd jacks installed or did a DIY installation on their MH. The emergency brake interlock switch that has to be activated before you can lower the jacks is intermittant on my '99 Jayco class C. I believe it is due to corrosion because of the salt air here on the Oregon Coast. What I need is the location of the switch. I did a quick look under the dash at the brake pedal area as well as crawled under and took a look at the e-brake area where the cable from the cab goes. I can't find it! Heck, I don't even know what it looks like! Anyone out there able to point me to the normal location (with the installation of a HWH-210 swing down jacks w/joystick)? E-mail to HWH has not resulted in a response either. HWH's repair manual gives the color code of the wires involved and test procedures - but not the location.

Thanks...........elp70

Do you have ANY switch on the brake pedal. IE: One that sets a lamp on your dash display?

Often it's the self same switch

Contact the manufacturer of the chassis.

i can't tell what chassis you have, but i'll take a stab at this...
on my moho, gm workhorse, the parking brake is actuated by a separate pedal next to the drivers door. the mechanism is above this pedal. the switch in question is mounted on the inboard side of this mechanism. it is a very flimsy loosely fitting white plastic switch. it appears that a plastic plunger fits inside of a track and is actuated when the parking brake is applied. sometimes i have to reach under the dash and wiggle it to make it work. the wires have fallen off of it once. i cannot see my switch from below without a mirror. i can feel it from the top with my dashboard open.
i hope this helps...
