I think the problem lays in the Pulse Module, perhaps the starter motor is getting continuous power slowly heating the fuse up until it blows. Could the solenoid be jammed?
The 20 amp fuse powers a lot of systems, all lower in amperage.
I am not so hot on sparky stuff though so this is just a hunch.
^^^^ It is a 50 amp fuse, not a 20 amp fuse.
I agree that if the starter motor were getting continuous power, then either the Pulse Module or starter solenoid is FUBAR, but wouldn't there be a heck of a racket from the starter staying engaged, in other words, if the solenoid is hanging, then the starter is engaged to the flywheel also.
The 12v to the starter motor is unfused, direct from battery to solenoid to motor windings.
