Need help with Acutemp Ax56l

PTB

Observer
I purchased an non-working Acutemp Ax56l. These are the military blood freezer / refrigerators in the hardigg type case. The batteries were pulled, but unfortunately the wiring harness was also disconnected from the power supply. The control board was also removed.

I have re installed the control board and believe I have the AC power wired correctly. The green LED lights up on the power supply when I plug it into the wall. The fuses are good.

Other than the LED on the power supply lighting up, nothing.

The 3.6v lithion battery (for memory?) is not installed. I also haven't connected the 12v leads from the outlet to the power source. Would either of those keep the unit from working?

Thanks.

Turns out the 12v line I thought supplied power from the plug to the power unit, actually pulls power from the power supply to the control board.

Now powered up!

Now I just have to fine the operations manual and sort out how to turn off the darn alarm!
