You probably have a battery drain from a defect. circuit. Just put a test light between the ground of the battery and the ground cable. If you have a drain problem, the light will go on. Then you remove the fuses one by one until the light goes out to isolate the circuit. A electrical wiring diagram will be appreciated.
AnswerParasitic Draw It sounds like you have an excessive "Parasitic draw" problem. It is called parasitic because when the car is not running, certain components feed off the battery, such as the computer, clock etc. When other components like a dome light is left on, it will take more energy then the battery can supply in a short time draining the battery. If you are sure that everything is off, including hood light, dome light, glove box light, trunk light, then your best to take it into an independent repair shop and have them troubleshoot it.

answerThe battery that is with the car when new is no good. I replaced mine with another brand ,Kirkland, and it's been OK since. Also the 80 amp alternator needs to be replaced with a 90-100 amp because of the accessories on the car.
disconnect the battery. Remove the alternator belt then disconnect the wires. Unbolt the alternator and remove. Bolt the new alternator in then connect the wires, belt, and battery.
from the back of the alternator to the dash to the battery
wires are crossed or you have a short in the wiring from the alternator to the battery.
The working principle of an alternator is like that of a small turbine. The alternator spins and a series of copper wires and graphite brushes inside the alternator produce electricity. That electricity is then transferred to the battery to keep it charged enough to run all of the electric parts on the vehicle.
yes if one of the wires was getting an earth from the alternator cover or rubbing off the engine the battery light is really an alternator light warning you that the alternator is not charging the battery
Obviously check the battery. Anyway, if the alternator, battery, and wires connecting them are good the voltage regulator is next on the list.
Wires between Alternator and Battery, and between Alternator plug connector and fuse box etc.
Disconnect the battery. Take the drive belt off of the alternator. Disconnect the wires from the alternators rear. Unbolt the alternator, remove, and install the new one. Reconnect the wires, belt, and battery to finish the installation.
Start checking your wires.
Disconnect battery. Disconnect wires from alternator. Loosen bolts and remove belt. Remove bolts holing alternator in place.
Disconnect the 1991 Regal battery. Remove the alternator belt and wiring. Unbolt the alternator and install the new one. Reconnect the wires, install the belt, then reconnect the battery.
Disconnect the battery negative. Loosen the belt and remove it from the alternator pulley. Disconnect all wires from the alternator. Unbolt the alternator from the bracket. Remove the alternator.
