Figured it out....DOH!
Mental note, do not de-winterize and get a trailer ready when it's getting late and you are tired.
I managed to somehow reverse the polarity when hooking up the batteries! Who new negative was white wires and positive was black
The thing that tipped me off was I knew the oven hood fan would turn one way hooked up correctly and the other way if the polarity was reversed.
So I disconnected the battery and ran off AC only....the fan turned counter clockwise, then I connected the DC removed the AC and the fan turned clockwise....thus I had the DC connections reversed at the battery.
The refrigerator needs to have both AC and DC to operate....so that's why it had no response no matter what, with the battery in the correct position it works fine.
Phew....I didn't even wreck anything else
