I am new to bass boat's and have a question about the batteries. I have a 1976 70hp johnson motor with 2 batteries, the first battery is a reguler 12v car battery "I think", for cranking. The other is a 12v trolling motor battey. My question is how can I tell if I have a alternator on the boat to charge the cranking battery or do I have to charge the cranking battery before each trip out? Where would the alternater on the boat be, on the motor?
thanks don
