Fuse with Powermaster anybody?

[Cupid]

I just got my 140A, 1 wire powermaster and stuck it on. I had to take a step back b/c I remembered my failed 3G attempt due to the infamous v-belt pulley goat rope...

Anyway, Powermaster didn't state you needed a fuse. They even provide the pre-crimped 8 gauge wire (which I promptly tossed to the side for a 4 gauge one).

Do I need a 175A wafer fuse for the Powermaster or not?

There have been instances of underhood fires when a diode in the alternator fails and shorts out. It is less common with new alternators, so a fuse is simply cheap insurance.
