Hello fellow NT owners:
I have a 2006 32’. My boat is factory equipped with an inverter/battery charger, and with four 6v batteries wired in parallel which are designated as the House battery bank. My boat does not have a generator.
In a very narrow space behind the house battery bank and the hull there was a fuse block screwed to the deck with a 300 amp fuse. I am sure the fuse to battery location distance was within AYBC specs, however that location left a 300 amp fuse hidden from sight.
I am not sure what other models or years have this design.
I must admit, after 9 years of ownership I paid little attention to the fuse or its location as basically it was “out of sight and out of mind”.
Recently searching for a dropped tool, I looked at the 300 amp fuse block and the cables leading to and away. I discovered that apparently over the years water/moisture caused the terminal ends and fuse area to turn green and corrosion was creeping up inside the battery cables.
Following the advice of a certified marine electrician, the 300 amp fuse block, and several battery cables were replaced and relocated to a back board located a bit off of the deck.
A battery on/off type switch was also installed in between the fuse block and inverter/charger.
The 300 amp fuse and the on/off switch are no longer out of sight.
May I suggest, that if your boat is set up this way, check the 300 amp fuse block, and the associated cabling.
I have photos if anyone has any interest.
Safe boating
