So update, 2 years later.
System was working great up to a couple weeks ago.
Unit would turn on , then trip the breaker after about 30 seconds to 1 minute.
Found the power input connector melted a little.
Replaced the connector and contacts, but no change.
Pulled out the multimeter, and found something in the condenser fan circuit was shorting to ground.
Unplugged the fans, the wires are open to ground, so they are good.
Found the rear fan on the condenser shorted to ground.
Resistance on front fan was about 1.22 k ohms.
rear fan resistance 0.5 ohms.
Tried to hook each of them up to a milwaukee 18V battery. big spark for the rear fan, front fan worked normally.
Removed the fan, found it was locked up.
Checked the parts manual for the ECV/REV trucks, all it shows is the overall assembly (unless I'm looking in the wrong spot?)
Fan assembly had the part number on it.
Rear fan is 4109028
front fan is 4109027
Entering those numbers into parttarget got me
4109028 shows as NSN 4140-01-548-1171
AM General part number 6015594
4109027 shows as NSN 4140-01-548-2496
