Ok after a few burned fingers and some choice words to the idiot that picked up the probe after he had sodered the new end on I got it working. Put 40 gallons in the new kettle and tested the set up.
It worked great (by the way it is a Brewmation retrofit I am using) and I did not blow any fuses.
The picture shows all our brewing kettles
The one on the left is the 20 gallon brew kettle / mash tun
Next is the new 55-gallon brew kettle
Next is the soon to be new mash tun
Next is the HLT
And the last one is our old tiny 15-gallon electric brew kettle
