I need some ideas. It is a Yamaha atv. Battery shows 12.9 volts and
turns the engine over fine, but won't start. When I hook up a battery
charger it starts right up. Battery voltage when running is 14 volts.

Any ideas?

Maybe a bad starter...loading a normal battery but having enough power

I had a "dragging starter" once. Armature bushings were bad and this
seemed to cause problems. The starter and cable would get hot, acting
foolishly.

I measured the Amp draw as the starter turned over ... I forget
