An alternator can charge normally but can still drain a battery if the diode(s) are defective. Try this: remove the(red) positive cable from the back of the alternator and then touch it to the post that you removed it from. Remember, this is hot so don't touch it to anything else. If it sparks this indicates the alternator is pulling current, and is bad.
I can tell you that on a 2000 mercury cougar it is a fuse on the positive cable between the battery and the alternator
Every time you disconnect a battery cable you have to reprogram the radio stations ( if that's what you are asking )
There isn't any fuse then is linked to the alternator on a 1996 Mercury cougar. The alternator has an internal regulator, but does not have a fuse.
wires, connecters, terminals
You can replace the alternator on your 1989 Mercury Cougar by removing the alternator belt. Disconnect the wiring harness from the back of the alternator. Remove the alternator retaining bolts. Reverse the process to install the new alternator.
Battery light usually means alternator not charging. Most common solutions would be be a bad alternator, bad connection, or loose alternator belt. If the battery and alt test ok than check the connections to the alternator and battery. You may also have a battery drain (something that is staying on and killing the battery)
the battery could have a dead cell, this could cause it to not charge. Have the battery tested to be sure.

This happened to me on a road trip in my 84 Cougar. It was a long time ago, but first make sure your belts are tight! But I believe you may need to replace the alternator. If the battery is old, its cheap insurance to do both.
start your car and then disconnect the battery if it dies then it is your alternator that is what i am working on right now but good luck if it is the alt you have to drop the motor cradle
Its a sign that either your battery or alternator is starting to fail.
If the bearings in the alternator get bad enough it can lock up.
It should be the same as for a 2002 Mercury Cougar which is answered in WikiAnswer under the Question; " How to remove alternator from a 2002 Mercury Cougar 2.5L V6." The 2000 Cougar may be different by having an upper alternator BOLT. If it does, and you can't lift the bolt out (after fully loosening the bolt), lower the alternator and you can, then, lift the bolt out. When you begin to install the alternator (attach the power wire, and the wire connector) place the BOLT in the upper hole in the alternator, and THEN, raise the alternator to install.
usually that the battery isn't taking a charge. have the alternator checked, many shops will test the charging system for free
It's grounded on the front of the Mercury Cougar frame next to the headlight assembly.
The charging system is the alternator which is on and functioning anytime the engine is running. If not, then you have a problem with the alternator.
it's inside the alternator, and is probabaly causeing overcharging of the battery (you might see white foam(battery acid)on the ground under the car) you can't buy and individual voltage regulator though, you have to buy a new alternator
Check for a blown fuse.
front of engine at top on right side facing engine
Faceing the engine.move to the left side of your car. Looking inside and down.Find your belt.Follow the belt and your alternator should be below it.
if it is a 2.5 v6 than take the passenger front tire off and the alternator is right behind the plastic shroud
The Mega Fuse is located from the alternator to the back of the engine, under the air filter.
Mercury Cougar was created in 1967.
If the gages in a 2000 Mercury Cougar at not working, it is likely that a fuse is blown. While the chance is slim, there could also be a wiring harness malfunction.
According to the 2000 Mercury Cougar Owner Guide : Both the 2.0 litre four cylinder and the 2.5 litre V6 engines came with the Motorcraft BXT-40R battery ( that's BCI group size 40R )
