Need to get a new solenoid. There's a million new ones on ebay under $10 bucks and straight from china. Im skeptical about the quality and how many amps they are designed (or not designed) to handle. Doubt there is any copper inside. Ayyone been using one? ok?
I'm thinking I might be better off getting a used one from a modern bike. This way you know it has atleast passed some standards. Like this one from a 2011 Ninja...

But why would there be 4 prongs? and a 30A fuse? doesn't the starter pull 100+ amps?
