I believe you,. I almost lost my Volvo a couple of years back because of no fuses on the wires hooked up on a inverter. I didn't install it, it was in the cab when I bought the truck. I knew nothing about that stuff. There was a little metal brass air blower that used to blow dirt out to clean the truck and it somehow got fouled up on the lug wires of the inverter. It was night time and on a 2-lane country road. Heard some sizzling and something smelled bad. Checked my mirrors, saw flames shooting out of my battery box. Needless to say, just like John Boy and Billy.....it was a sphencter tightening episode. Got it put out thankfully but the wires were toast. Yessir no fuses. Getting ready to install another inverter but with good fuses.
