I'm having some problems with either my battery or the charger (or both) and I'm not sure how to troubleshoot the problem.
When I first got the bike and would charge the battery, I would hear the fan come on inside the charger, and the light on the charger would turn yellow (if I recall correctly) then it would charge for a few hours, and then the fan would turn off and the light on the charger would turn green. All charged up.
Now when I plug the battery into the charger, the fan never comes on and the light on the charger turns green, despite the battery being completely dead.
In addition, the light turns green when the battery isn't even attached!
Any ideas how I can verify if the problem lies with the charger or the battery?
