I have a sullair 185Q. Built in 2000 caterpillar 3054 with a 1.tamp electrical drain when system is off key pulled. Drain is gone when I remove the ramp inline fuse from the wiring harness located near the starter. Ideas would be appreciated on how to fix.

Follow the voltage. If you luck out, you'll notice it is lower as you get to the drain. Reference to the inline fuse.

Alternatively, if you have or can get a DC CLAMP-ON ammeter, you can use that.

Sorry, it's tedious.
