If you have a test light available disconnect the negative cable and connect the test light to the cable and to the battery.If it lights up you have a parasitic load.Something is using power when it shouldn't be. A very dim light or acceptable parasitic draw is about. .015 amps depending on vehicle options it could be all the way up .025amps. If the test light is pretty bright it has a large load pulling it down. Finding parasitic draws can be quite time consuming. You can leave the test light connected and start pulling fuses one at a time till the light goes out or gets very dim. This can help you find what circuit is causing the draw. Once you find that particular circuit you will need to find out what services that circuit supports. Example the cigarette lighter may run the accessory lights such as the dome. You will need to find out what is on the circuit to start figuring out which component is dragging the battery down.

You have got something in the vehicle pulling the battery down,check the hood light,and the trunk light,and the clock can do this also,along with the radio.

What caused new battery to die?


lack of proper charge rate from the alternator is the first place to look
has to charge 14.5-14.8 volts DC or the battery will go flat quickly
next batteries have a warranty period for a reason and brand new is no guarantee to long battery life
take it back for a load test and then have an accredited auto electrician test the alternator

Crank sensor, ignition module under the coils these all would be good places to check. You might want to see if there are any codes.

1991 Park Avenue: new battiery will not hold charge...


Check the following to see if your cars electrical system is causing a power drain.

*Make sure all headlights and interior lights, and accessories are off when vehicle is not in use.

*Have your alternator professionally tested to make sure the built in power regulator is not going bad. Also check that the alternator is putting out a proper charge during vehicle operation. (Use a digital multimeter, touch the test leads to the battery terminals while the car is running RED to positive+ and BLACK to negative-, being careful you don't cross the two and never let positive and negative touch. Multimeter should read 14 volts DC with the car running. If it reads under 14 volts, replace the alternator.

*Check for a bad grounding wire (usually the negative battery cable), if it's cracked, frayed, or bare wire is exposed replace it right away. It can drain the battery if the bare wire touches the metal of the vehicle.

* If your car is equipped with the twilight sentinel (automatic headlight feature) shut it off manually when your done using your car for the day. If the twilight sentinel is going bad, it can draw battery power even if the headlights are off.

*Have a test performed to make sure you don't have a faulty ignition switch. This can draw power even with the ignition key off.

*If all of the above test good, you likely have defective battery. Replace battery. Feel free to contact me if problems persist.

Good Luck!
