I have a problem with my Norcold refrigerator in my 1978 Revcon coach...when plugged into AC, it will show ac on the display on frig, but after 2 or 3 days the display blinks and will say Lo DC. If hubby puts the charger on the engine battery, the frig will run fine, showing AC on display for 2 or 3 more days. It keeps draining the engine battery.
Here are my questions:
1) What's happening, why is the frig running the engine battery down?
2) Why isn't the frig running off the coach batteries?
3) Why isn't it running off AC when the coach is plugged into an outlet?
4) The batteries, all of them - 2 for coach and 1 for engine, are 4 years old, are they too old?
I sure would appreciate any help...
