Limited DC power
So I pulled my 2016 274DBH into a campsite and plugged in. I am getting AC power and the accessories are working. The slide works (both on and off shore power). The fridge works (on ac power and when just powered from the battery via the inverter.
HOWEVER, I am not getting any other DC accessories powered (lights and thermostat). It will not work on battery alone nor when plugged into shore power. The battery is good. The circuit breaker under the trailer is bad, and the converter maybe bad (repair man here now). However, we are unsure what has caused the converter to go bad or blow the breaker between the battery and the trailer.
Also, how do I go about getting my warranty to refund me paying a mobile repair shop?
