There is no power any where in the cab, i have just replaced all the fusible links and there’s a new starter and solenoid. I think it could be the fuse box but i’m not sure. If it is i have no idea how to go about replacing it… Any tips or ideas?

Using a test lite, do you have power to the fuse box?. How about the main connector on the firewall, you should have a wiring diagram to help you with this.

No, i tested all the fuses and there is no power in any of them, with or without the key on. Nothing happens when i turn the key. Im not sure where else to test for power to find a problem. My uncle is looking for a fuse box today at the scrapyard, if that is probably the issue

Gotta check for power in and out of the main connector on the firewall.

No, the junction on the firewall where those connectors meet, there is not power. And i just replaced the fusible link right there leading up to it as well

Welcome to the site.
Is there power at the firewall fused link? It has a stud and bolt through it. It's next to the brake booster.

What was done prior to power loss?

Hey, thanks for your response. Sorry my wifi was out for a few days. I isolated the problem to a faulty fusible link that i thought was good, and i had just installed. Reinstalled the wiring to the solenoid, and she fires up! I do not have power to my gauge cluster though.

Probe the instrument fuse for power. Was the cluster removed? A ground could be missing.
