I replaced the stator on my bike today and my lights all came on but went out my plug is now not getting any fire what could be the problem.

 

There's a 20 thermal circuit breaker in a sealed pouch up from the battery. If you don't have power on both sides of the breaker just slice the pouch open and see if the breaker terminals are corroded. You can replace this at any auto supply.It supplies the main power to the lights,ignition switch,etc. If this doesn't help,no spark could be from a bad cdi,coil,wiring short or even the stator you installed. Best to have a manual that shows you step by step on finding the problem rather than guessing or throwing parts at it.2003 Polaris Predator 500 Service Manual PDF Download
