Best way is to disconnect the neg cable and put a meter/test lamp between the neg cable and neg post. If the light shines, pull fuses till the light goes out, that will be the circuit.
If you don't want to disable the computer, use an ammeter and keep the connection between battery and cable alive throught the meter.
Hooking up your amp meter will be tricky try this method. Loosen the neg. battery cable, slide the cable upward, connect your amp meter lead to the exposed post under the cable. Connect other meter lead to cable, remove cable completely from battery post. An alligator clip/s on the meter will help.
If done carefully, it will save having to reset the electronic gizmos.
Don't forget that bad diodes in the alternator can also cause a parasitic drain on the battery.
Let us know how you go with it.
