Electrical troubleshooting

[USN_Green_Addict]

I am in desperate help on how to troubleshoot my truck. I have no power to any accessories with the switch on, no fuel pump, no starter, no lights. All of this was working a month ago. I have bought a test light and a harbor freight volt meter. So far i only see power directly off the power post of the starter. Its an 39Mt starter I do not have the old big relay attached to the block. The truck was running and starting one month ago. So where do i go from here and how?

I'm guessing it's an M35A2.

Someone has replaced a cable.

It looks like wire 10/14 is missing, according to the schematic available on this site: https://www.steelsoldiers.com/threads/peter-bogs-cad-deuce-schematic.3843/

Wire 10 feeds the ignition switch after connecting with wire 14 at the relay you said you don't have; without it, you will have all the problems you've described.

someone could have relocated the 10/14 wire over to the + 24vdc battery post, and its now not connected, or it broke off from corrosion or over aggressive wire brushing.

To be honest, I haven’t figured out how to use this new site yet.

I’m trying!

As for finding your own threads/posts, I think you can simply click on your user name at the top right, then click on it on the next page that opens, then find your threads and get to your threads/posts from there.

Found #74 is blue wire, #5 goes to the battery. Still can't seem to find #10
