You might be able to trace current draw if you measure voltage drop on fuses too. Multimeter in lowest voltage mode and probes on fuse (if there is metal nubs on fuse to measure from). Higher the voltage = higher current through fuse. Depends on fuse ampers, higher=lower voltage drop per amper.
If some fuse stands out, there it probably goes.
