Battery draining

My 1992 Caddy Fleetwood, front wheel drive, all electric, if let sit some times 1 day the brand new Diehard battery dies. 875 CCA. This is the replacement for a Gold duralast battery. I found one problem the antenna motor was constantly running. I have noticed that the level control compressor runs even when the ignition is “off”. {the compressor comes on as if to level the car then shuts off}This has been a problem for a couple of years. Any ideas? Battery charges to 12.50 VDC and ALT output 14.25+/- .50 VDC.

THANKS.

I am pretty sure the compressor coming on and off is normal, even when the car is off. Check your terminals and battery cables, could be corroded

Put a 12v test light between the battery terminal and the cable. If the light comes on, start pulling fuses til it goes off. That will identify the offending circuit.

Tried the test light test....light stays on.

Just went through the same thing on a 91 caprice that I had. I spent 2 weeks tracing wires and checking voltages, to no avail. Wound up selling the car.

Not quite the answer I was looking for.

Start pulling fuses til it goes off. That will identify the offending circuit.
