Hello

I'm trying to get an old Transicold Supra 644 to run.
The diesel engine of the cooler was stolen from it, someone just cut off the wires.
So I try to get it to run with only the standby motor and I have a few problems with it.

The controller gives me a few errors which I don't know how to solve them.

- No power

The display says no power allthough I have power applied and the motor runs if I turn on the contactor, in the circuit diagram I found the Detector Power Supply but I can't find it on the unit.
Could someone tell me where to find it or take a picture of it?
I assume that I have to apply +12V to some certain wire to get this error solved

-WT sensor

Is this the temperature sensor of the cooling water of the diesel engine?
Does anybody know which kind of sensor this is, so I can place some kind of resistor insted of the temperature sensor.

Thanks in advance for any help.
