Hey everyone, I am having some troubles with a 2007 500 EFI X2. The bike is not charging properly. I am getting 12.5V to the battery, until I turn the headlights on, then its down to 11V.

Any help would be greatly appreciated.

I'd have the battery load tested even if it's new first. If the battery checks out,connections are tight,then probably charging problem from the ecm(pdm) module. Item#15. Dirt Cheap Yamaha, Honda, Arctic Cat & Polaris OEM Parts & Accessories – Cycle Parts Warehouse

 

Thanks OPT, I was kind of thinking the same thing. Battery is good, and all connections are tight. I believe this year was known for ECM issues.
