They probably blew a diode in the alternator and/or fried the voltage regulator. Take the alternator back and have it diagnosed outside the car.

SOURCE: 1999 ford escort zx2 alternator works brand new battery but battery isnt charging !

Stecorbett:

May I suggest that you drive your car to one of the major auto stores and they can and will check your alternator for you to make sure it is good/bad.These places like AutoZone do this all the time. They do not charge for the check out. (Of course they are hoping that if you need a part you will buy it from them.

One other suggestion. If you do need a new alternator, get a rebuilt one. It is cheaper and most always comes with a warranty.

Hope this helps Good luck Loringh PS please take a moment to give me a rating

How long did the 2nd alt. last before it died? The voltage regulator is, I believe, attached to the alternator. Have u had the voltage regulator checked?

As dumb as this may sound check the termials and if the u-shape is up then flip it over. I had the same thing happen to me on mine and now it works fine.

If you get no red light for the battery charging system the charging system will not work. The indicator light initally excites the field to start charging.

Hooked up my new battery backwards, blew the main fuse. It has been replaced and now the meter fuse in the inside fuse box blows within seconds and gage cluster and alternator not working


Could have damaged regulator. When the car is running have you checked the voltage at battery terminals. If battery is charging it should be around 14 volts. If around 12 your charging system is fubar.

Meanwhile if you have to charge the car every day then something in the car is draining the battery, Using an ammeter you need to track it down, Hook it up to battery and pull fuse out one at a time till the drain goes down. That isolates the circuit with the problem.

Battery light stays on 2001 lincoln continental


battery light stay on because there is no output or below voltage out put from the alternator. Check that the battery terminals and posts are shiny clean and tight, if there is a charging circuit fuse (OK). Have the battery load tested . Remove the alternator and have it bench tested by an accredited auto electrician.

May have blown the diodes in the alternator. But first check that your fuse and fusable link are good. This website may help.

Battery will take a charge from a charger, but will not charge from driving. Alternator is ok


the alternator charges the battery thru the heavy lead on the back of the alternator that goes to the battery. make sure it is clean and tight. the alternator output should be 13-15 volts with engine running.

New battery drains.


I can't imagine how changing the belt would have any effect on the electrical system if the alternator is working.
The way you check for a drain is to disconnect the battery ground cable and use a test light to make the connection between the battery and ground. If there is something drawing power from the battery the light will glow.
Then you pull each fuse from the fuse boxes until the light goes out. You also disconnect the starter and alternator if necessary.

I have a 1999 Mercury Sable and accidentally installed the battery backwards. Replaced blow fuses and the car ran fine. After sitting idle for 3 days, returned to find the new battery dead. A jump start...


Check and make sure your termimals to the battery are clean and tight. You can find out if the alternator is charging by simply starting the car and while it is running take the negitive cable off the battery. If the car quits its not charging (have the alternator check) if the car keeps running it is working properly. If it is charging and all your termimals are tight and clean you may have shorted out the battery and ruined it by hooking it up backwards. Good luck
