;Multiplex Problem
« on: December 23, 2017, 04:32:01 PM »
I have an 06 Beaver Marquis and having a problem with Multiplex.  I thought it was the switch plate in the gally with 10 switches.  Aqua Hot button would not work.  Then i noticed the water pump button had a problem also.  This am I turned everything off, batteries and shore power and inverter was off.  When turned back on everything came on water pump turned on and aqua hot also, but after a few seconds the aqua hot light went out and it would not come back on. It ran its normal tiime and turned off, but you get nothing after that.  The water pump basically the same way comes on and goes off.  Tried all diffrent switches for water pump inside coach all same.  Turn on outside and it works fine. All help appreciated. Love the Forum.

Bobby, suggest you check your multiplex control master for a red fault light if illuminated. Ours control panel is located in the bathroom with the main 110 AC panels. Turning off house and engin batteries should reset your multiplex system. Also check to see if your water pump fuse green light is illuminated on the mutiplex panel. Also multiplex plates sensitivity can be adjusted by removing the plate and tighten the stand off screws.

I do not seem to have a multiplex control panel.  Have multiplex controls in ovrhead above driver, in bath below main power panels and one behind storage cabinet in gally slide by the spice cabinet it is velcroed on back of panel. Everything is still a mistery. Turned everything off for about an hour with same results.  Also the vent fans do not work.  All lights are fine window shades are good. I am at a loss about multiplex control panel. Thanks for the help.

Well it was one of those problems that seems to fix itself.. Dont know what changed but will take it.  Turned everything off same as have done several times before.  This time turned water pump on inside coach it worked fine, turned on fans and they worked fine.  Ran water several times pump worked fine. Turned Aqua Hot on it came on and fired up.  Hapy days are here again.  Thanks for the help.  Merry Christmas
