Engine Wiring Harness Block

[tgtaylor64]

I have a M1009 and I am trying to determine what some of the wires are that are attached to my 12 VDC harness block on the firewall. According to TM 9-2320-289-20, page F-11, there are only four wires: 12 VDC feed from the (-) battery #2 (rear), two blue wires that are together that feed to the alternators, and an orange wire that feeds to alternator #1. I have two additional wires on my block that go to thick red wires in the wiring harness that the others feed into. Is there another wiring diagram that I am missing, perhaps updated?

In addition, TM 9-2320-289-20, page 4-89 shows only four connections (one is the 'double' blue wire), for a total of five wires. To clarify my first post, I have four connections, but on splits into two blue wires before the fusable links. I have a total of five wires out.

You have to look at ALL the diagrams.

The 6" of wire is the fusible link. Not the black plastic connector

I dont have the -20 diagrams in front of me but the -34 diagrams should be the same and are labeled "E"

E-1 shows the 12v feed from the battery (1-blue)
E-3 shows two feeds for the fusebox and ignition switch (2-reds)
E-9 shows four feeds for the alternators (3-blues and 1 orange)

Have you ever looked at the first few pages of the Troubleshooting Section? It tells you how to read the diagrams and how to read the wire labeling.
