Hello, my name is ***** ***** I am going to assist you with this.

Code 45 is Speed Sense Fault.

The controller senses engine speed by the frequency of the AC output, so the first thing you need to do is to connect a frequency meter to the unit, and verify the frequency it is putting out while trying to start it.

What frequency reading do you get?
