Well that is a good and easy test. The alternator you just replaced is probably bad. Once the vehicle starts its the alternator's job to keep the vehicle running. You need to take that alternator back to the auto parts store and exchange it for a good working one.

I hope this helps you out, if it does please give me a YES that I did help you correct your problem. Thank you.

    I am having the same issue....however I have replaced the battery four times,rebuilt the alternator and put two new alternators in the car and it still will not hold a charge. At this point I am putting the car on a charger every night just to drive it aroud 1 to two hours the next day, and during this time I cannot turn on the radio,lights or air conditioner because it drains the battery and that is all I am driving on. The alternator is not charging AT ALL...so don't waste your money on another one. The alternator will ALWAYS test bad on the car...then test perfectly fine off of it. I have done some research and many people are having this issue. Ford has a recall on the battery cable being misrouted but most people have a car conveniently NOT included in it,although it was manufactered during the SAME time. Mine being one of those not included. I did come across someone who replaced the MEGA175BP Main Power Fuse on the cable from the starter to the battery. She said it was broken and would come out causing random electrical issues. I have not tried this yet...as I am still trying to find an exact remedy to the problem....but I am starting to doubt that there even is a fix. I'm just at the point where I do not want to waste anymore money. Only a handful of people have actually kept the car long enough to get this resolved (the girl who replaced the main fuse and others who had loose fuses but not the root of the issue), while others just get rid of it. At this point...all I can say is try the main power fuse and cross your fingers...I'm going to try it as soon as possible.

I have a 2001 Mercury Cougar that the battery drains if I drive short distances, then it will not start, altenator is 20 months old so is the battery, Just got a complete tune up 1 month ago


Either the alternator is not charging the battery, because the belt may be loose, the battery cables may be corroded or loose, or the alternator is faulty.
The battery may not be taking a charge, there also may be a light staying on in the trunk, glove box, or under hood.
I would have a reliable auto center perform a load test.
Please let me know what you find.
