    Mine is connected to the house battery. Someone rewired yours. My amp would last about 15 min on my old house batteries.  Actually it was my best indicator that the batteries were going bad and needed to be replaced.

    No, it should definitely be wired to the house battery.  Should be a red 2-gauge wire direct to the battery.  Sounds like somebody accidentally connected it to the wrong battery.

    thankyou for the response, the daughter and son in law had the boat out and told me when they shut off the stbd guest batt isolator the amp shut off also.
     that would mean the feed for the amp would come from the load side of the switch
    and not direct from a battery. think i better do some more investigating

    It's only the stereo head unit that is wired to the battery switch (or, on some boats, to an ignition switch).  The head unit has a separate wire running to the amp that turns on the amp when you turn on the head unit.

    The amps are wired direct to the battery.

    Although, this schematic shows the head unit connected via the DC Main rather than the battery switch.

    Where is that 7 amp fuse located? Someone was asking a while back. I think on a 342 it is on the main cabin panel.

    i think that 7 amp fuse location is the key it needs constant power for the stereo memory  ahunting we will go starting with the line side of that 70 amp fuse

    The stereo memory is what keeps your preset stations in the radio along with the clock.
