maybe the batteries I have are bad or something. Cause when it was sitting in the back yard where it used to be. If I let it sit to long, the batteries got really low, and then my voltage reg thingy (yes im blonde) would start screaming, and completely drain the battery. what do you mean by turn on the main power switch pete?? you mean just the propane right? to run the fridge? im learning as I go, so no comments from the peanut gallery on this please.
