Alternator
How did you determine that "there is not current being produced to charge the battery"? If you are basing that on the state of the battery maybe you are expecting too much. It takes quite a bit of running time to charge a dead battery with the output from most small outboards.I would check it with a multimeter as was already suggested. If it is putting out the appropriate voltage the perhaps you have another problem. Maybe you are just using more than you are producing. Or maybe you have something that is draining the battery when you think everything is off.If you provide more details may someone can give more advice.Pete
