STUCK ! NEED Help with 12V Fuse

[Studman]

Calling out for help from the almighty searay gods!
Only the 2nd overnight trip on the boat and decided we needed a 12V coffee maker.
Started making the coffee and while waiting decided to play with the GPS.
Somehow somewhere the main fuse popped.
Lost all 12V recepticles, GPS and accent lighting.

Anyone know where a major fuse would be?

Checked all fuses @ battery from the charger, looked behind dash, checked under (helm kind of).

Anyone know where it would be?
Please help, stuck in Mystic....

Boat is a 1993 290 DA 7.4 liter all 120 works on shore power

Lost all 12V recepticles, GPS and accent lighting.
And how many would that be.most wiring is maybe 14Ga rated for 15A . usually just get 1 outlet at the helm for a plug in spot.
Do the other items work off the 12V panel?
Just a guess but do you have a panel behind the steps to the cabin area,28 coastal puts the battery switches and main system breakers there.

I don't believe your 12v adapters are rated to run something with as much load as a coffee maker. Have you ever looked into the propane powered coffee makers?
