I blew a fuse on my brand new 2020 Triton 18tx on about my third or fourth trip out, about a year ago. What a hassle that was.
Since that ordeal, (like you), I made sure I had every fuse I needed (from then on) very close at hand... with a voltmeter too.
It's amazing how little things like that can take the starch out of a fishing trip right quick.
