I have a 20hp mercury outboard that has a conection the size of a small finger that you can connect to your battery and charge your battery while running the engine. My question is I have the wire harness that connects from the battery to the finger size conection on the motor. Do I need to have some kind of voltage regulator or someting of that sort? Or can it be connected and charge my deep cell battery as I run my engine.
Thanks for any help.
