Wiring Diagram for 1945 Pepsi Cooler

[Dmaher]

I have a 1945 Pepsi double Dot water box, the one where you just put water in and coils chill the water.
I am trying to redo the wiring and hook up a new compressor and agitator.
I am unsure if the relay switch has gone bad or if the wiring is backwards.  Does anyone know where I can get a wiring diagram to make sure it is all connected correctly.
I have new 14 gauge wire, new comprssor and new agitataor, but nothing is getting power now after the relay switch. 

I appreciate any help

thanks

Welcome aboard Dan!  I am sure that somebody on this forum can get you all of the information that you need but 

Please post some pictures of your cooler so we can identify the make and model.  You will find that the people on SMC.com are very helpful!

Measure from the relay contacts to ground & see if you have line voltage present, if you do, then you may have an open neutral, or you may have two "hots"  on the line feeding the motor, then you'll have no return path, therefore no current flow to power the motor. good luck "sparky"
