Default fuseable link - where is it?

I have a 99 Ranger 4.0. I just replaced the altenator, then the battery idiot light started coming on and the altenator gauge still shows no charge. I have had the battery checked twice and changed altenators twice. I did bugger up the plastic connections that go into the altenator, so I bought used ones at a salvage yard. Ford doesn't make those anymore.

In my quest to fix this, it has been suggested that it may be the fusable link. Where is it? Near the solenoid was suggested to me, but unfortunately, I don't know what it looks like or where it is. (My dad and brother got all the mechanical sense, both gone). Any suggestions for me? Pictures whould help. Thanks for any help.

If your 99 is anything like my '93 setup the harness that directly connects the alternator to the rest of the wiring harness IS the fuseable link...

So just follow the 2 platic plug wires from the altenator (3 total) back to where they come out from a more numerous set of wires? What do I do? Cut the 3 wires there and replace?

Fusable links are off the battery side of the fender relay, and should be marked. You will need a test light or meter to check them. Unless the wire is burned, you will not be able to tell if they are bad by sight.shady

Thanks Shady.

I have been told so many things I feel lost. The if I take it to be fixed, it will be more than $100 for something I could do. All the wires are covered with black heat wrap. How will I find the fuseable link? I am a dummy.

It is the BIG wire that connects the alternator output to the battery terminal on the starter relay.

The field wires are "bundled with it"

If you replace it as an assembly it's a three minute job,
no cutting, no splicing, two nuts.

this fuseable link is a big fat one...

Thanks AD,
So it is the big wire attached to the altenator with a nut (not the plastic clips) that appears to run over to the battery positive connection through the power distrubtion box that holds the starter relay? If so, no wonder I haven't found anything...I have been looking from the 2plastic clips attached to the altenator back.

So is my interpretation right? The wire you are talking about is "bolted" to the altenator and "bolted" somewhere over toward the battery? Replace that wire and be done?

Yeah, the main output wire from the alternator IS the fuseable link...

Or atleast it is on my 1993 Explorer setup...

It is the ONLY fuseable link in the truck... well actually there
are two of them... connected in parallel, because my setup
uses the 130amp alternator.

The "fuseable link" you have been looking for is about the diameter of a pencil.

SAFAIK it is the ONLY fuseable link anywhere on a 1990-up RBV.

at the body end it is connected to the battery stud on the fender mounted starter "solenoid"

The large wire to the alternator will have battery power all the time. Use a test light to check the wire. If it lights the light, the fuse links are good.

One of the wires in the plug will also have 12vdc when the ignition is turned on, and 0 when off. This wire has nothing to do with fuse links. The other wire on the plug goes to the battery light.

To see if you really have a problem, you need to check the voltage across the battery posts with the truck running. It should have around 14vdc, +/-.

I checked the wires on my 94, and it has three coming off the fender relay battery positivie. One large one going to the power distribution box, no fuse link, and two gray connecting to a large black/or that goes to the alternator. The gray wires are fuse links.shady
