Hello all, new to the forum and just got my first Suzuki. Was gifted a 01 gsxr1000 that has issues I'm trying to sort out. Previous owner stated he thought it needed a new starter relay. Got the bike home and battery was shot. Put a new battery in and turned the key but did not hear the fuel pump kick in. While I was looking at a few things my son pressed the start button and almost immediately I heard a puff and smoke came out of the ecu! So that's now fried but I can't figure out why it fried. Best guess is something wasn't hooked up correctly. Disconnected the battery and pulled the ecu. The plugs for it were warm and the back side of the ecu had a burn mark. Where should I begin in diagnosing the issue? Dont want to get a new ecu and have the same thing happen. I would have thought there would be built in protection to keep this from happening.
