2001 F-350 7.3: I thought the batteries were dead, but they are fully charged. I've got NOTHING. No guages, no horn, can't jump the solenoid. I replaced the start switch just over a year ago. Where to begin?

Check your fuses and fusible links. On the 97s the fusible links were tied to the hot side of the starter solenoid. They look a bit like wires.

I have power at the hot side of the starter solenoid, but still nothing powers up inside, nor will the engine turn if I jump the starter solenoid. Have not dug into fuses yet. Is there a fuse or relay that would cause this problem?

Hmm....Surprised no one had an idea. I guess I'm getting it towed to a shop. I have checked every fuse in each block. It's honestly as if there's not even a battery in the truck.

TMS,

Sorry... busy evening. If your coil is like the one in my 97 the big terminals are the relay (the switch) and the small terminals are the coil (actuator). You should be able to bridge the big terminals to see if the starter will kick over. This just sends power to to starter solenoid coil and it is reasonably low current. On the 97 there is one big red wire that comes from the battery into the relay (on the big terminal) and then there are 4 or 5 smaller wires that go out from that same terminal. Where the wire leaves the terminal is where my fusible links are. One of these links supplies power to the key switch which provides power to the fuse box.

Edit: the fusible links are covered with shrink tube.

If jumping both large terminals on the fender relay does nothing, I would take a very good look at battery connections, and the connections on the other side of the cables. Especially the ground wires.

No worries. I appreciate the advice. Are you talking about the starter solenoid on the inner fender? I've tried jumping that, but no luck. There are two solenoids on top of the intake near the fuel bowl, but I do not know what those do. Seems like something farther back in the supply thought, since nothing powers up in the truck at all

The two on top of the engine are the glow plug relay, and the intake air heater relay.
The one on the passenger fender is the starter relay. The starter solenoid is on the starter itself

Thank you. I should have remembered that. I had to replace the glow plug relay on a 97 I used to have

I had the same problem, mine sat for four years, cause no one could figure out,..... Accidentally discovered it was the fuse block next to the steering column. Apparently on these trucks water gets in around the windshield and ends up behind the fuse block. I replaced it, and bam..... Fired right up. .... Hope this helps
