HEy guys, I have an 84 westy and recently pulled my fridge to install the GW aux battery, fan kit and the new CHeck valve kit.  When the van is plugged in to power the fridge works great.  Whe I switch to Battery power while driving (or even sitting in camp as I have the aux battery) the fridge does not work.   ANy ideas as to what might be the issue if it runs on plug in power but not DC?   Also still havign issues lighting the thing on propane but another story.
