BEP 717A-100A 3 battery mounting at stern. Relays can be seen, top row, at the left and right of the House battery switch. Emergency Parallel switch for the 2 start batteries is in the bottom row, middle, directly below the House selector switch. These switches are all in the "ON" position. This allows GUEST 2610A Charger to charge the 3 on-board batteries. The how: the charger is wired to the Starboard and House batteries directly, allowing the Port to be charged via the Parallel Switch. When either Start battery reaches 13.7V the VSR will cut in, the charger can thus support them all.
