Update to the saga - and man am I appreciative of all this information!
My tested salvage unit was delivered to me from AZ RV Salvage in Glendale, AZ on Friday.
My HVAC guy and I set aside today as the install date, and we got to work on it this AM. Following all the previous user instructions, we got the old unit out and new unit mounted up in testing position with little issue - though when connecting all power to it and running the initial test, compressor 1 did not kick on, though after the minute or so time gap, #2 fired up no issue and started blowing cold (HOORAY! - sort of).
After a few line tests, we discovered that COMP1 is completely grounded out, as it kept throwing the circuit on the generator when we'd do a direct test - further line testing show it completely out of whack (OHM readings) when adding everything up.
They claim to have tested it, but when the unit arrived, they had 2 jumper wires on the white and black lines for 120v circuit 1 and 2. HVAC guy said they wouldn't have tripped anything with the jumper on - as it should have been tested individually. As it stands, I've contacted the seller to lay out the issue and see what they'll be willing to do - as at this point, we either put in a new compressor and all is set to go, or we see if they have one in stock that has both functioning compressors and they verify to ship out to me in a swap.
SO - sort of back to square 1. At least at the moment, I get 70 degree air blowing off compressor 2, just not enough to really cool it down.
Double bonus - my tech will run through the unit we pulled out to see what can be done with it.
Getting there... little by little...
John Canfield - I kept seeing your trust but verify post flashing in my head as we were getting it set up
Will update when I get a response from them.
