I have an '83 FC, so there may be differences.

The 3 switches above the drivers left shoulder that are labeled Air Conditioning. Each powers a relay if they are left on, so shut them off.

Get a helper to turn the DC power switch under the right side of the dash off and on while you listen for the clack of a relay energizing. Once you find the relay figure out what it does and decide what to do about it.

I once had one of the VentLine roof vent's (circular) motor freeze up. No clue why my parasitic load increased by 5 amps until I happened to turn it off on a whim. Discovered the motor was pretty hot too.

Get a good digital Amp Meter and keep an eye on the load.
