Unless its in line at the power supply there is not a fuse. That fuse would be on the power supply line which goes only to the LSS 1 box.Last edited by Bass Cat Boats on April 9th, 2014, 2:08 am, edited 1 time in total.
There is no”fuse box” on a BCB. They use circuit breakers and a terminal block in the rear of the boat, usually on the inside drivers side transom. Your Lowrance may have an inline fuse from its power source at the starting battery.
