Another idea would be to check overall harness resistance at the battery cables. --

with the car , off , cold, key removed etc.

-- undo both battery cables, -

Measure resistance in OHMs for the harness (one lead on the - bat cable one lead on the + , NO BATTERY TOUCHING .

-= , it should be just about open.

if you want to find out how much your MSD leads are drawing, you can remove the MSD battery lead from the solenoid and observe the difference.

if the issue is somewhere else , you can isolate by pulling and replacing fuses 1 by 1 until the resistance goes away.

There are some items that require constant voltage. - clocks, computers with memory, radios with memory, alarm systems.

but in a simple car like the Cobra, there should just be about NO draw at the *all-off* point.
