Location: So. Illinois | Will it cause any problems to hook up a fishfinder to the motor starting battery. Is there any chance any damage will occur to a fishfinder if it is on when the boat motor is cranked? I have a friend who told me not to connect a fishfinder to the cranking battery because he blew out his finder when he cranked his motor. Any thoughts would be appreciated. |

| Seeing as how most power blocks at the console get the power from the starting battery, anything that would happen by connecting to the battery, would happen when connected at the console. Not to worry. Connecting directly to the battery is the preferred method. As mentioned, use an inline fuse. Most sonars come with a holder and fuse. |

| I have hooked my Garmin to the starting for all last season and the four outings this year. It is always off when I start the Honda. I really dont know if there is a fuse there or knot. |
