    Some boats have relays and diodes for the hatch override posts at the top.

    On mine, 2 are for up/down of engine hatch.  The other 3 are for the blowers.

    hmmmm, now I am really confused, I thought they had something to do with the remote battery switches,  My port remote battery switch will only turn off, and the switch itself is a on-off-on type switch, that is why I thought relays were involved..   Back to tracing wires for me.......

    It’s possible that the switch failed.

    I had to replace one of the rocker switches for the remote battery switch as it failed. Maybe try swapping the port and starboard rocker switches. They just pull out.

     Bought a new switch.  Did not fix it.  Why would a on-off operation have an on-off-on switch?

    Maybe I missed it, but what switch has failed? Power? Breaker?

    the Power switch failed, BEP 722.  I replaced with a BEP MARINE 701-MD Remote Operated Battery Switch

    So you figured out the on/off/on for the switch. These bigger boats if you are just getting started are a handful! I have 8600 babbling post over like 10 years- would not have made it without this forum.
