I gotta 2000 Yamaha warrior 350 that I recently replaced the salanoid on, but when I tried to connect the battery it sparked and even started. The ignition was off and the key out. So I'm wondering what the problem is, because the wiring is correct

 

If it started or even tried to start with the key off then you have a wiring problem!! Afactory service manual will show the correct wiring

 

Ok, I'll check the manual
