Going back to electrical, and it's a long way back so forgive me if I do the math wrong. But at full load the AC compressor is going to use 1650 Watts of power. To do the same with a 12v system you need to be able to provide continuous 137.5 amps. That's a lot
Yeppers, 110v can do the same job with a lot less amperage than 12v can. You could still use the tank and get a different compressor, but I think you would be wasting an otherwise usable compressor considering you can get a 7g tank for less than $20.
Sell the compressor, use the money to buy your 12v setup.
Contra, does your Jeep have A/C? If so, does it still work?
If it has A/C and it doesn't work, why not convert to OBA?
If it doesn't have A/C why not grab the bracket and compressor from the wrecking yard and put OBA in. You can use the tank, safety valve, gauge and pressure switch from the 110V compressor. All you need is the hoses, oiler, dryer and a couple 3 way manifolds.
Does anyone know the output on an a/c compressor? I'd bet it's really high (good thing)... I had a spare a/c compressor that had a separate oil sump so it could run for a long time without burning up...
And all of the diodes may have committed suicide, leaving you with a fun whirly thing under the hood that produces nothing.
