I Keep popping 15 amp fuse

[Benlugchev]

I Keep popping 15 amp fuse on my wire coming off back of alternator going to my "hot" power block

Does my wiring seem correct, it is based off research i did on this site and other forums.

Battery has 2 wires - 2ga to post of starter - neg to frame

Starter has 3 wires -2ga from + batt
- 10ga from big post to back of alternator
- purple wire from factory harness to little post

Alternator has 3 wire - 1 wire in plug that goes into computer
- 10ga coming from large post on starter
- 10ga with 15amp fuse going to constant "hot" power block


Harness only had 3 relays Fans, Fuel pump, IGN. (no other fuses)

- 2 wires coming off relays that called for "key hot"
- 5 wires coming out of harness and relays that called for "12V hot"
- 3 ground wires
- relay ground wire

Headlights/gauges are running off the stock harness/fuse box

Truck is running very rough and will barley idle. Seems to be misfiring
