Okay here's an interesting situation for all you pro's out there. I got an 1986 F-250 Diesel here and when I went to start the truck, I lost all electrical power. The batteries are fully charge and load tested within stanards.
When I got into the truck, the dome light was on and buzzers were ringing away like they should be. But as soon as the ignition key was turned everything went dead and has since remained dead. And the key wasn't even fully turned before it died. In looking under the dash and under the hood, there is no visible signs of anything shorting out. I took a test light to the fuse panel and everything is dead except for one fuse that supplies the emrgency flasher and nothing else. So out of curiousity I pulled the hazzard switch and the lights do blink. But nothing else on the truck works. Everything was working fine three days ago when I pulled it up into the driveway and shut her down.
Now could there be a short in the ignition switch killing 99% of the electrical system without draining the batteries, or is the problem much deeper than that? I don't really want tear the steering column down and pull the switch if that's not the problem. Kinda of lost here.
