We purchased a 4yo 2016 Tour Ext. Previous owner was not the gentlest but we've gotten most of the issues resolved except electrical issues.
1. New house battery. Two days of success:
a. Driving, all 12v
items powered successfully. Inverter was online
seconds after engine started and successfully powered 110v system
b. Shore power at RV site successfully powered all 110v and 12v
Inverter remote showed battery on "float"
2. Day three...
a. While driving, radio would periodically shut off and within five
minutes restart. During time off, no information displayed on inverter
remote. When inverter remote came back, was able to turn on (get
green light) and power items in the rear compartment.
b. Shore power (after letting the vehicle cool down)
i. Engine off, inverter showed red light and "FAULT, No Comm". No
services worked. Power control panel will not show amp load
or service (30a vs 20a vs ...)
ii. Engine on, inverter showed red light and "FAULT...". After 20 sec
or so, heard click from driver's side rear and 12v sources came on.
The red light and comm failure still are displayed
Dealer originally found that the breaker on the line from the house battery (underneath, behind driver's side rear wheel) was tripped. I've verified that it is not tripped with the symptoms above. So I'd like to get as much data as I can so the dealer "can do the right thing". I'm not afraid of using a voltmeter, but crawling underneath and disconnecting cables violates my insurance policies.
So, I'm thinking...
2(a) seems like a thermal breaker issue with the off and on. But, the vehicle had cooled down.
2(b) seems like the shore power is not being detected by the inverter and is preventing it from functioning.
Thoughts? Avenues to explore?
