Hey all - I have a 2008 Starcraft that I am having power issues with. When I plug into 120v the outlets and the microwave work, no fridge. The only way the fridge comes on is if the microwave is running. The fridge will not come on under battery power at all, same with the lights. I have the checked all fuses and wiring but no issues. I am thinking the converter is bad. Thoughts?
