hey i have a question, i have a 84 yamaha 225dx that keeps blowing fuses every time i turn the starter switch, i think its just a basic short but how do i be sure? could there be short in my battery? i have put a new circuit relay on, a new starter solenoid, and i have taken the left side apart and checkd the magneto and the flywell, i have spark but the engine wont crank over, and also the thing will sometimes start in different gears instead of just neutral thank u
