I have the factory installed electrical package. New boat.
However I cannot get the electrical system to work. I suspect I am missing a ground wire. How many ground wires run to your battery? At present I have only one ground wire which runs to the battery charger. Can anyone tell me where the main ground wire runs from the battery. Any suggestions?
