How would anyone provide help without a wiring diagram?
That is what you need
You don't replace any part without knowing how to test them
& the parts you replace have to fail a test or your wasting your
money on replacing perfectly good parts
I would replace the Fusible Link before you do anything else
How could some help when you have no vehicle shown on this site? Get a wiring diagram & learn how the system your having a problem with works, so you can properly test it & find the problem

First check alt At The Back of Alt Big Red Wire Were hooks to Post (stud) Do you have voltage ?? How Much??
What Voltage do you have at same Place with Engine Running ??
Now At wires Were they plug into Alt ,Top. Wires in White Plastic Clip, Do You Have Powe With Key On ?? How Much Voltage??
Jump across the 2 in the clip (with Engine Running)ONLY TEMPORARY!! Do You Have Voltage at Battery ?? How Much??
If Over 13volts With Clip On (Jumped) You Need A Internal Voltage Regulator ..
Is Batt Light On on Dash ??? Theres A Lot Of Testing You Can Do !!! And I will Need More Infomation to Keep Going ... These are just some Possible Problems No Way In Depth ...
Could Be a Number of things Or May be Just as Simple As a Blown Fuse, Dirty Batt Cables ETC etc etc I Hope It Puts You On The Right track !!!!!!!!!!

SOURCE: NEW ALTERNATOR, NEW BATTERY, CAR still dies and wont start

Check the main power fuse that goes to the alternator output. if the alternator went out it could have burnt this fuse also.

SOURCE: Charging light come on after alternator replaced

No fusible link, make sure the wires connected to the alternator are making good contact. If you installed a rebuilt alternator, it could be defective. Also check the voltage regulator

SOURCE: Need help replacing fusible link connector

It doesn't matter because they all carry +12V to the respective circuits. What does matter is which fusible link goes to which circuit (assuming they are different) but if you didn't cut them off, then they should still be connected to the correct circuits.

SOURCE: Daughter called me wont

it sounds like you have blown fuse to the Alternator.. I don't know what car you are talking about but they charging systems vary.. But if alternator isn't getting all the power it needs it won't charge. this should be checked.

good luck

Battery not charging new alternator still not charging

Did you check power an grounds at the alternator ? The heavy gage wire on the back of the alternator should have B+ voltage , if not fusible link is blown . The connector ,pin's 1 & 3 should have B+ voltage also . There are videos on youtube on checking charging systems . Do you know how to do automotive electrical testing ?

Fusible link?????

Normally the "Fuse-able Link" is right next to the Battery. It'll be a short length of wire supplying all the current to the fuse box.But this won't be the cause.
I have a problem with your description "Battery still dies while driving around". Can you elaborate on this?
Assuming the Battery and Alternator are not defective, the fan belt is tight enough and the Battery is fully charged, all should be ok.

Check for B+ voltage at the back of the alternator ,the heavy gage wire . Then there is a connector with two wire's the red wire should have B+ voltage as well , the last wire (BRN) should have B+ voltage with the key in the run position only . Not chaging probably . Maybe you blew a fuse or fusible link .

Yes a bad battery can cause this problem. Pull out the battery and take it to have check also. But, your wiring to the alternator maybe at fault. If your alt. is good but, it is not charging the plug or a wire may not be making contact. Check your battery. Check for any broken, burnt loose wiring. I know you just had it out. But check the wiring at the battery. The smaller wires are whats called "fusible links" meaning they are fuses. Tug on them a bit to see if inside the insulation you can feel the wire separate. Hope this helps Fix Ya up.

I don't know what type of vehicle, model or year, but it sounds like a blown fusible link. This is not a fuse, but acts like one. They are generally wired in at the starter after the positive cable connection (again I don't know what vehicle). Sometimes they are wired directly off the battery at the positive cable. On the trucks they can be at the firewall R/S relay center. Regardless, most fuse panels, alternators and cooling fans are controlled by a fusible link. By you jumpering the fuse boxes you are just taking place of the blown link. They are usually in-line (mostly large red positive wires. They can be a black bulge in the wire or just covered with black heat shrink. Follow all the leads from the battery and locate them. Test after the fusible link for power (use a test light if availible).

Click on the link.
The diagram shows generator with internal voltage regulator and with external voltage regulator, at the moment, I don't know which one you have?
The bat terminal at the generator should be hot even with the key off, is it, use a test light. If no voltage either the fusible link is faulty or the wiring circuit to battery +. You can see fusible links in diagram.
Could be other issues, the generator probably needs excite voltage or it won't work. The excite voltage comes from charge indicator circuit. Does the charge lamp on the dash work?

The car died randomly and it seemed like the alternator was the problem. i replaced the alternator and the prblem occurs again where all the lights in the car, radio, and even the car turns off. the batter...

First thing is to ck the charging rate of the alt. It should be between 13.6 and 14.2v. Checked at the battery terminals. The lower the voltage the higher the amps. So, On a low batt, you would want around 13.6v and a fully charged battery around 14.2v.. Test alt with engine running, note charge voltage with everything off. Turn headlights on and charge voltage should drop as low as 13 volts. If volt reading is at or above 14.2v, the alt is putting out minimum if battery is full harged. Proper battery connections are very importantand battery to engine connrctions, especially the ground bolted to the engine should be double ck'd.
Here is something to note!
Fords use fusible links in the charging and other electrical circuits. A fusible link is a lentgth of real small wire that burns in two if the wire is overloaded or shorted.. They look like cylinder made of rubber on a wire. To ck, pull easily on both wires going into and coming out of the rubber cylinder. If it stretches, the fusible like is burned in two. More than likely it will be in the group of wires running across the top of the radiator.. If it needs replaceing, fusible link wire is available at the parts store. Good Luck Ned

1994 Mazda Protege, new battery, new alternator, wont charge

You must have blown a master fuse or fusible link.

Refer to the maintenance manual.

this happens sometimes during a jump start or a direct short in the elect system.
