I had an issue with battery being ran down after my Craftsman sat for a week between uses. Traced the issue to parasitic leak thru the key switch. Switch always worked, never would have suspected it to be bad.

Wait until you have one blowing the ignition coils at random. That one can get expensive fast.

Once you have the wiring diagram, remove the key switch and measure the continuity across all connections. Verify that there are no shorts across terminals that should not be connected in all key positions. When connections should be shorted, they should be a solid connection and not varing.

Perhaps the wrong replacement fuse was installed. Was the original a Time Delay and the new Fast Blow? That's critical.

A possibility why the fuse opened in the first place: Fuses can go bad over time due to periods of vibration. The flat element vibrates its brains out. Kind of like bending a paperclip back & forth a bunch of times.

I had a similar problem years ago. I found a wire that went to a headlight had touched the exhaust pipe
and shorted out. A little electrical tape and moving the wire back into it's clip solved my problem.
