Hello fellow Monacoers.
So I have a multiplex system in my 2008 Navigator. Runs off a PMC CPU model 02b - 320 channel. I believe this to be the Intellitec system and not the Kongsburg)
I have read and read what I could find about it but need to ask for insight as I'm stuck.
My whole system died as I hit the main living space overhead lights. Everything is dead in the water. Macerating toilets, overhead fans, rope lights, slides etc. (Really need slide control).
I verified it's getting about 19.7mv to the CPU and each relay box. Fuses all look good. Grounds look good as well. Batteries showing 13.5v with my multimeter at the terminals and also on my inverter/charger controller.
I used the salesman switch to kill power and hopefully reset the CPU. Didn't work. I also did a soft reset on the inverter. Nothing. Then proceeded to try a hard reset for 10 min. That didn't help. Getting a bit desperate now.
Anyone have any insight beyond what I've tried? I'm pouring over the long post about the 09 Signature that had to be totaled because of lightning. I'm just not very well versed with this system.
Not exactly what I wanted to be dealing with on Christmas Eve and now Christmas day when no one is available to come help with it. Any help would be greatly appreciated.
*EDIT* I might add, none of my relay modules have an LED light on. I *think* they have them but have never noticed any on, but then again I wasn't looking either.
