ford alternator voltage regulator wiring problem Sign In

I have a 66 F100 that appears to have a 351M and FMX transmission We bought it for a cruiser and when the alternator stopped working, I met a kid at the parts store that had a similar set up and bought the alternator he recommended. I couldn't get it wired before I forgot his instructions and, when I returned, he didn't work there anymore. I took it to a mechanic to install and I don't think he knew what he was doing either.

alternator- stamped on top x74a e93rba 3 4 9 b (I think) without removing it, I see two large black wires with orange stripes and a white wire with a black stripe coming out of the bottom and a plug at the top with the following wires a green with red stripe, white with black stripe and yellow with white stripe

current set up-
both white with black stripes are not connected to anything
green with red stripe goes directly to the ignition switch
yellow with black stripe goes through a 30amp in-line fuse to the positive
both orange and black wires connected directly to the positive terminal and fused with 20 amp push in fuses (wired in-line)
there is a voltage regulator mounted to the fender wall with nothing attached

problem-
fuses on the black wires with orange stripes keep blowing and thus not charging the battery

so far-
the black wires with orange stripes are producing over 60 volts

how do I correctly wire this and, if i need another voltage regulator, which one do I get?

Thanks!
