Question about 1995 Buick LeSabre
The battery won't hold a charge, the alternator is good and the battery is new, no electricity at all in car.
Replace battery....you may have a parasitic leak electrically...once in place use a test light in line between batt ground terminal and metal ground ....if it lights brightly you need to begin pulling fuses one by one to make the light go away or become very dull (computer and radio use tiny amounts of keep alive current) which is normal..once you have isolated area that is sucking power you can advise or fix and repair

SOURCE: Car won't stay running.
alternator does not hold a charge it simply charges the battery by unhooking the battery you are taking all voltage from computer and car will not run the proper way to test your alternator is use a multimeter and check voltage at battery while car is running if you have 13-14 volts it should be fine.

I don't know how you figured out that your battery was good, but if it drops to 9 volts I highly suspect that it is bad. You need to have it load tested. This will tell if it is bad under load.
Also if it is bad it can cause the alternator not to work even if the alternator is brand new.

HI. you may have a battery drain issue that is sapping your battery overnight.
Here is the procedure I use to isolate a battery drain. Remove negative battery cable from the battery. Using a 12-volt test light, hook one end to the negative battery post the other end to the negative battery cable you just disconnected. The test light will glow or "light" if there is a drain. If the "light or glow" is faint, that is probably normal draw for the clock or computer. If the "light or glow" is bright, then there is a large drain. That should be corrected. Now start removing and replacing the fuses one by one until the light goes out; that one will be the circuit with the drain. Remember to hold in the button in the door jam for the interior lights.

You must have a bad gound somewhere or faulty wiring. Your not able to get current from your new alternator over to your new battery properly.
Source could be poor or dirty conections, a corroded ground wire or a bad conector at the alternator itself.

Hello and welcome to FixYa!
If the battery light is on, I strongly suggest that you have
the battery charged. It can be an indication of a weak battery or a faulty
alternator. If the battery light still on after charging then the problem will
surely be on the alternator itself. If that's the case the alternator should be
replaced to resolve the problem.
If the battery won't hold charge even on a new alternator
then the problem will be on the battery itself. It surely is in the end of it's
service life and replacement will be necessary.
You may try to reset it to by removing the positive battery
connector, letting it sit for at least 5mins. then reconnect it again. This
will reset the system and can get the battery light off.
Hope this helps and thank you for using FixYa! Have a good one!
