Sounds like their is a draw on the battery when the key is in the off position. Check the draw on the battery with the key in the off position. You can do it your self or at your local auto parts store. If their is more than what their is supposed to be then their is a component that is not turning off.

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. The Belt needs to be Pretty Tight. Please Rate My Response! Thanks!

    Sometimes it can Feel Tight and Still not be Good enough to Charge. You should not be able to move the Belt at all up Or Down.

Hey Steve, if you need a jump to start it then every thing is working except battery holding power try putting battery on a SLOW charge for a day then try again when its running check output of altinator with a fully charged battery it should be 12.5-13.5 volts and rise when you rev motor up ,when you jump it im thinking the battery is very low and the altinator is trying to recharge battery and it cant do that in just a few minutes running time or take it on along ride and watch amp gauge .good luck Steve.

The altinator is missing ground, any time you remove the battery and the engine dies, that only means that the altinator is not charging, there has to be a fuse for charging systme.

I have 2 problems 1. my low coolent light keeps flashing an staying on its full of fluid an 2. good battery in car changed altinator an now the battery wont hold a charge what could the problem be


The switch in the coolant tank that turns the light on can stick due to contamination from old coolant.Replace this switch,or leave it disconnected.If your battery drains overnight,there is likely a draw,possibly trunk ot glove box light on.If the problem started when the alternator was replaced,it could be a shorted diode in the alternator.

Altinator wont kick on and battery wont hold charge


Ask dealer about TSB's. Bulletins on those issues. Sorry ,but that is a nice vehicle but one of the worst products on the market and I mean of all things we buy,not just automobiles

1991 Dodge 4x4 truck altinator will not charge, new altinator, all fuses are good and serkets. Altinator will not charge.


Change voltage regulator. Does the battery take a charge from a charger? If not, replace battery. If it does, then regulator is faulty. If still nothing, return alternator to place of purchase, and have it checked.

My battery light is staying on in my 92 lincoln towncar


Get out a volt meter, With the car not started check the battery you should be getting round 12volts.

Now turn the engine and check the terminals again you should be seeing about 13-14 volts. If its high it means the regulator on the Alternater has gone and it wont charge the battery because to much going to it and that would cause other eletrical issues, and if its low your looking round the same problem with the Alt.

Also check the serpenteine*sp is not to worn as it wouldnt be turning the pulleys as good and would cause issues as things can't work correctly.
