Fault finding.
If you take the accu lead off does it spark when you reconnect it?

Take out all fuses, be sure which carrier slots they came out from so you don't swap the values about.

Do the spark test each time and narrow it down to the circuit which draws current.

Then it is a matter of tracing the wiring, the on off switches of the item concerned if it is not on all the time.

If you have a DC ammeter you can put that in series to check what load you are drawing from the accu which may give you an idea which may be at fault.

Good luck
