You can just try stuff, kinda hit & miss, the likely candidates have been the Radio, Instrument Cluster, Alternator. Unplug or pull a fuse one at a time maybe.

From there, you could just pull fuses in groups to try for a change.

There is always the "Draw Test" where you monitor the amount of power the system is using, then pull a fuse at a time to direct you to the circuit that might be the problem (NOT as easy as it sounds.... ) Of course, many circuits are supposed to be consuming power all the time.

If you have the time, it's far simpler to just "Pull & Wait" to see what happens.....
