Bill, am i replacing the entire white wire i have drawn red arrows on in my picture and putting a fuse in line with it?

Yes on the white wire. That first picture is a good one showing both white wires in the lug at for the alternator "B" connector.

EDIT: also another stupid question, but i'm about to head to the store to get wire and fuses.....

I got a 130 amp alternator. Should i go with the 250 amp inline fuse or is the 125 amp you pictured enough? Also, this is a really stupid question and shows my wiring intelligence, what is the 100-300 amp fuse block for?

I had heard that the circuit should be fused approx. 20% more than the capacity of the alternator. So roughly 150 amp would do it. Very important - fusing a circuit protects the components but also the wiring. In other words a 150 amp fuse won't work with #18 wire. The wire will burn up before the fuse blows. So a number 4 or larger wire should be fine for this distance. Just get 4 lugs that will work with the wire. (alternator to fuse block - fuse block to battery positive)

EDIT2: ok i think i answered my question about the fuse block, it's just a gizmo attaching the two ends of a wire and the fuse sits in the fuse block, right?

Right, the 100-300 amp fuse block means it will work with a range of fuses from as small as 100 amp up to a maximum of 300 amps.


I should not muddy the waters but sometimes it is helpful to know other alternatives.

Alternative: Leave the stock wiring connected to the "B" alternator post. Run the new larger wire and fuse as we have talked about from alternator "B" to fuse to battery positive. Then just disconnect (unbolt) the little white fuse link wire in AM1 little black box in your first picture and wrap the end with tape to keep it from shorting.
Pros: This eliminates the stock large white wire and fuse (fusible link) while keeping the connection to the small white wire down at the alternator for the fuse boxes. It also eliminates having to crimp in the small white wire with the new big wire at the alternator.
Cons: It does leave having the "B" post doubled up with the two wires so not as clean of an install.

I hope this is reasonably clear.
