Miramar 33.5 Electrical Issue
Help with an electrical issue;
2016 Miramar 33.5
Problem with monitor panel and water pump:
Water pump will not turn on
Monitor panel status lights will not illuminate when buttons are pressed
All other functions on the monitor panel work;
Gen starts/runs from panel
Both slide out functions work normally
Both water heater switches work normally, 110/gas
Everything else on coach works as advertised, no other electrical issues. Problem is intermittent, occurring twice now. During this event the battery volts are reading 13.6-14.9 volts, as read from the Xantrex 1800 Inverter, (depending if the engine is running).
Problem occurs regardless of source of power, AC shore power, Genny or Xantrex 1800 Inverter as well as on 12 volt battery power!
I checked battery state with volt meter, with no load-batteries were reading 13.8 volts.
Latest event occurred at repair facility, the technician removed monitor panel and checked all connections, they were good as well as all fuses; everything checked good. Lastly he checked the water pump volts behind the monitor panel, to his surprise they were only reading 4.6 volts.
The tech removed his hat and scratched his head! He said he would need the coach back at a later date for a couple of weeks to troubleshoot!!
I've tried turning the store/use switch on and off, drove down a bumpy road, looking to see if it's a lose connection, nothing has worked so far!!
Anybody have any ideas or solutions?
Thanks,
