Battery going dead but altenator checks ok? - 1999 Ford Taurus

Sounds like your altenator is bad you can check it by unhooking the battery while its running and if the altenators bad it will go dead.

Have you taken the battery to autozone or someplace and had the battery tested? I would find if you know the alternator is good it must be the battery itself. Might want to try that if you havent already. Good Luck Bro~

ALtenator runs your car while it is running and charges your battery. If your altenator is bad you car will run on the battery until it drains the battery dead. So no the altenator will not prevent you car from starting. Check your fuses.

are you sure you're not leaving any inside lights on inside? if so, check the battery for a dead cell, have the battery load tested. if not that, check the altenator for bad diode. can buy a rebuilt altenator for it. or if you choose, new one for it. just to be sure you cover all bases, check to make sure your altenstor belt is on it. i hope this helps!!

Hi,

The clock & radio usually share the same accessory fuse.

1. Check the 10A Radio/accessory fuse in the cabin fusebox and replace if blown.
2. Check the fusable links from the + (red) battery cable to ensure they're ok and secure.
3. Check accessory relay, in engine fusebox.

Please advise outcome...

As long as you have had the charging system and belt checked and they are o-kay. You should be alright just make sure you disconnect the negative battery cable before starting. If the charging system wasn't checked have it checked first. Depending on how the battery goes dead you could have adraw on the battery, a bad battery, a bad belt, broken wire, bad fuse link just to mention a few. Be sure before you replace alternators are not cheap, not being sure could be an expensive mistake. Good luck.

check ur alternator

Your bettery is probably bad. Replace it. Also, have your altenator checked.

Have the altenator checked.

Check your Belt Tensioner. If the Belt Tensioner is Not Holding the Belt Tight Enough it will not allow the Alternator to Charge the Battery. Let me know. Please Rate my Solution, I need all the Help that I can Get! Thanks!
