Wiring help - fusable link burned out

Message Topic Search Topic Options Post Reply Create New Topic Printable Version Translate Topic

   I was poking around under the hood today to wire up my electric choke, and I found a burned up wire when I pealed off some electrical tape.
The wire itself is connected to the sta post of the alternator (the sta wire also has a factory y off into a different set of wires).

Burned wire goes to this connector on the passenger side of the engine bay:

The only non-burned wire in this set connected to anything is the red one that runs to the starter solenoid.  Other end goes to the empty harness shown below

What wire have I burned up?  Could I solder in a modern fuse holder instead, if so, any idea what size fuse? ( Blue block on the wire says "fusible link 20 ga")

Edit: the car still starts fine, so I'm not sure how long this may have been burned out for before I found it today, possible it's been this way for years!

	Have you looked at the wiring diagrams? https://forum.grantorinosport.org/wiring-diagram-downloads-for-torino-montego_topic17676.html My '72 doesn't have a plug like that so I am not recognizing that wire off the top of my head. If you can't figure it out, I will take a look at the diagrams when I have some more time. CaliforniaJohnny is more familiar with the later Torinos, he might know. Why not just replace it with fusible link again?

	I believe the alternator's STA stud and it's wiring goes to the carb's electric choke. Here's a wiring diagram showing as such, it is from a '75 Ford shop manual but hopefully it is helpful.

	A new fusable link or a maxi fuse . But FIRST !! You have to figure out why the original fusable link took a hit and burnt . Obviously a serious short to ground on one of the main circuits! Find that first !
