I don't run any fuse, but I've heard that a 200amp fuse is recomended.

so would it be safe to run no fuse at all?

I run a 200 AMP circuit breaker fuse. I know people running without a fuse, but it's probably not the best bet, if something happens you'll kick yourself in the ass for not buying a 13 dollar part.

can I do this and just run the stock 2 wires and an extra 6-8 gauge with a 100 amp fuse ????

Under no circumstances connect the two 10 gauge black/white wires to the 3G alternator. If the fuse blows in the 4 gauge wire, the two 10 gauge wires will be overloaded to the point of catching fire and burning up the wiring harness.

Use a 125-150 amp fuse for 4 gauge wire.

Having a problem with the intall. I mounted the alternator and tried to install the Ford OEM pully off my original alternator (1991 vintage). When I tightened this pulley up, the alternator won't spin freely with this pully. Do I need a pully off an SN alternator or I am I doing something wrong.
