Yeah I'm just completely stumped. I figured out if you press the buttons on the roof light it turns on and if you open the back doors it will come on. If you press str on the radio the time shows for 5 seconds ish but I CANNOT get power to the key, gauges, actual radio, or anywhere else. I'm just at a complete loss here

I'm wondering if the ignition switch is fried

Is there a way to check without changing it?

You'll need to come up with a wiring diagram so your not just shooting in the dark

 

[ak diesel driver]

You should be able to test it with a DMM but again a diagram would be helpful

I have one but its incredibly hard for me to read

Ill go take a video of what I have going on and see what you think

 

[Landon730]

Don't have a diagram but I believe that wire supplies power to that block.

The 2 small wires on the big posts of the starter hook together at that master. It was like this when I got it

looks to me like they were trying to use that disconnect switch to activate the starter

where does the small wire on the starter go to? Into the factory harness?

Not totally sure yet I haven't traced it but Im pretty certain it does because it is a factory wire

So what I would check next is to see if you have power to the prurple wire going to the starter when you hit the key. If not then I would back probe the yellow wire off the ign switch to see if it's hot when you hit the key

Did you watch that video at the top of those pictures? I can't get power to the dash either unless the wires are hooked in this configuration but its still not right

 

[ak diesel driver]

when you say this configuration what are you talking about?

The way the wires are hooked up on starter and that cutoff switch. If I take those wires loose I lose all power at the dash

what if you temporarily run a wire directly from the battery to that stud on the firewall?

I didn’t and that’s how my dads truck is wired to minus the two wires that are in those picture

This might be a problem

Looks like something added on, trailer brakes?
