80 Amp Alternator Fusible Link in 1994 4x4 Pickup 22re
So - I live in the sticks and our driveway/lane is gravel, steep and washed down to the large base rock after the last monsoon season.
The majority of the rock is nearly the size of my fist, so it's a bumpy ride, no doubt.
I noticed that the speedo would stop working from time to time and the tach would jump around as I climbed the drive. When the speedo was in it's broken state, there was also a noise/whistle in the dash speakers (radio off).
I assumed the bumpy drive had knocked a wire loose in the dash based on proximity of the tach, speedo and radio.
On Saturday, the Toyota wouldn't start as we headed home from a trip to the grocery. A guy was kind enough to push us (backwards) and dumping the clutch started the 22re right up. Made it home with no issues minus the speedo.
I pulled the cover off of the fuse box on the inner fender to find that the 80amp Alternator fuse/fusible link was gone.
There two copper metal pieces simply bent over (with pliers, seemingly) so they made (some) contact.
It appeared that a previous owner tried to remove the 80a fuse without visiting this site to locate the proper procedure and destroyed the fuse.
So - they bent over what was left of the fuse to bypass it and make a solid connection.
I picked up two 80a Littelfuse replacements at O'Reilly's Auto.
I got two as I assumed there was a lingering problem that caused the initial issue and subsequent hack job.
I figured the first one would blow in installation and I would need the spare.
I then proceeded to pull the fuse box apart to replace.
I found a lot of melted plastic under that particular fuse socket.
Luckily I located a replacement in a local salvage yard for $25 for the fuse box.
I pulled it apart and swapped out the fuse socket, installed the new fusible link and we are up and running.
Just posting for entertainment and in case someone has a similar experience.

With no apparent issues until this past week, I'll admit that I didn't look under the fuse block cover until Saturday. Just simply had no reason to suspect the hack job on that fuse. Sure, the truck had a leak g exhaust manifold and the fuel lines were swapped causing the charcoal canister to puke gas, but nothing electrical.
You can bet I'll add it to my own pre-purchase inspection from here out. LOL
