Battery Charger Location

[grantma7]

have a 73 pearson trawler and need td o know if anyone might have a book on the underside, where the tools and battery charger is. My batteries need a external battery charger and I can't find the Bat charger inside the boat. does anyone have a book like that??

Find the batteries and follow the wires- one will lead to a box with most likely a thick cord running to your breaker box and also may have a little light on it or an amperage gauge.
