Looking at previous post, I see I'm not the first or the last to hook up an inverter with reverse polarity. Was too busy talking and not paying attention! No smoke; but sparks. Anyway checking inside I find 10 ea 25 amp mini blade style fuses bridging the positive lead in on the circuit board blown. Figure it must be part of the reverse polarity protection. I temporally bridged across the fuses and the invertor came back to life.
My question is why are 10 25amp fuses used in lieu of a 250 amp single fuse? The fuses are fastened directly to the board with lead solder and something additional like an epoxy under the solder. I believe I saw somewhere the blades on the mini fuses are aluminum.
I haven't used this unit but a couple of times in the last couple of years; but don't want to chuck it if I can replace fuses of bridge the circuit with a single fuse.
Any suggestions would be appreciated, Thanks
