Battery terminals are clean ?

Battery is actually fully charged then tested at a shop where they can Load test it ?

Fusible link blown in main wiring to cab located about 18" from starter relay ?

Yeah what Mil1ion (Dennis) said. :)

But you can't "see" the trouble you need a meter to find electrical problems, so "looking" ain't gonna do it. Sorry. :/ It just ain't. :/

You know someone's messed up when they swap out a few electrical parts and it still don't work. A cheap analog meter could have told them exactly where the problem was to start with -for free-.

Pok, know anybody that's got a meter and knows how to use it? :)
Call 'em and have 'em show you how you use it while he finds your problem. :)

Time to call in a favor or be on the hook for one. ;)

Fuseable link is good Battery tested good. Have voltage in wiring harness as it goes into firewall but no voltage at fuseblock. Is there a term block somewhere inside the cab?

The fuse block is the only power block

power at firewall !

Then there is a problem with the fuse block

Disconnect the battery and pull the fuse box off to have a look at the back of it.
sometimes they corrosde so back they short out.
