Fridge runing all weekend ?

I've taken five days off and didn't have a problem. But if you do have a problem starting your tractor, especially if just completing a 34 hour restart, then it's time to replace the batteries.

 

Aftermarket fridges do drain batteries. Original volvo fridge will not. That is the short and simple answer. Friends aftermarket drains after one night my volvo fridge ran 2 days no problems plus it wouldve turned off fridge to prevent drainage to make sure truck had enough juice to start. If overnight your rear fan on dash is blinking, somethings been left on and drained your batteries and the trick unplugged it by itself basically
