Been searching the web for a bit, cant find answers.
Here is my deal....
I have a 2006 Alfa 5th wheel that is permantly hooked to shore power. Never move the trailer.
I have noticed the 12V system is not working at full power. Water pump, fart fans, lights, exhaust hood....
1) Do you need good batteries for a converter to work?
2) because I am on shore power 100% of the time, do I even need batteries hooked up?
3) my 12V lights are dim. 120 v seem to be fine,AC, TV, Micro all working fine. Seems like all 12V systems are low on power.
