wiring was as instructed. the two orange black wires crimped and soldered to the terminals provided, these as well as PA power wire went to the gold terminal, then the black white wire soldered onto the supplied white wire. power wire kit with fuse mounted on battery tray and hooked up to the + on the starter solenoid. belt is still on tight. wish I had my multimeter and it wasn't Monday (I rush off to school and then rush back to 2nd job.)
The instructions you have ae not correct. Under no circumstance, connect the black/orange wires to the 3G alternator.
Here is the reasoning behind using only a single 4 gauge fused power feed to the alternator. If you use the two 10 gauge black/orange wires in addition to the 4 gauge wire, you have two fused power feed paths. The total current capacity of the wiring is the sum of the fused paths. The 4 gauge path is fused for 125 amps, and the two 10 gages wires are fused for 60 amps. That is a total of 185 amps, which exceeds the capacity of the alternator. Overload can occur without the fuses blowing, damaging the alternator.
The worst case scenario is that the alternator develops an internal short to ground resulting in a catastrophic failure. The initial short circuit surge current is limited by the resistance of the wiring. The current in a parallel circuit divides up according to the resistance of the branches. If the 4 gauge fuse opens up first, the two 10 gauge black/orange wires will be carrying the short circuit surge current. Depending on the time lag of the fuse links, they may open up before a fire starts or they may not.
