fusible links?

[tsmall07]

So I finally got my truck going the other day and I've been getting it ready for inspection. I was wiring up the horn today (not the stock way) and all of the sudden I lost all the power to my fuse block (which my new electric fuel pump is running through). The only thing I can figure is that I fried a fusible link somewhere. Anyone know where they are?

only link is off the junction block.... do the wiggle test and see if it comes back to life.

There is more than one fusible link. Look in the back of the -20 for the schematics. You can find them all there.

If ALL of the 12V power is gone, you probably popped the main fusible link that is in the line from the battery to the diamond shaped junction block above the master cylinder.

Not all the 12v is gone. My dash lights still work. I think they're 12v. I'll look into it tomorrow.

So it turns out the circuit I tied into for the fuel pump was controled by the blackout switch. I accidentally flipped the switch so no fuel pump... I spent several hours undoing everything I had done and then I figured it out. Sometimes I feel like a moron.

Thanks for the follow up. At least you figured it out.

I fixed a few things that needed to be done from the PO's work. This truck has so much hacked wiring it isn't funny. I think I have fixed all the major fire hazards. I found a wire today that was strung loosely along the frame and the insulation had been melted by the exhaust. I really need to get the truck next to a stock one so I can really figure out what is supposed to be there and what isn't. The PO even tapped into a fusible link for power to something and he almost never used wire connectors. Most of the joints were twisted and taped.

is this a bad fusible link/

The blue wire is a fusable link. The outer housing is compromised. It may still conduct electricty but needs to be replaced.

FYI, If you do need to replace a fusible link, Napa has the wire in small coils and you can just cut and splice it in with butt splices.

Don't mess with it. Replace it.
