Battery is good. Alternator is good. Connections have been replaced and tightened. Starts ok, but after you drive a few miles, it dies. It will start back up sometimes but keeps dying. After it sits for awhile (maybe hours or overnight), you can start it and drive it again.
a 6ya Mechanic can help you resolve that issue over the phone in a minute or two.

If all your connections are clean and sound, then your car should be able to run without a battery. Start the car and disconnect the negative terminal. If it stops your alternator is faulty. This would explain dim lights that are draining the life out of the battery instead of being alternator driven. Same as the dieing while driving, the battery can't keep supplying power forever without being recharged by the alternator.
If the alternator is ok, the battery needs replacing. Repeated draining of batteries kills them.
Check and clean and tighten all battery, starter, and alternator connections. Also the battery and engine to chassis grounds. Did you have the battery " load tested" as a good test requires? Take the battery out and have it charged up. If the alternator is good, you should not have any more problems. But if you need a jump after a few days to start it, then either the alternator or the battery is just not up to par. Have the alternator tested while on the car and running. Good luck.
this once happened to my car. I was driving on expressway and all of a sudden car quit, then the gauges went haywire. and the dash light symbols all lite up.what my problem was is I just got done doing a major repair on car and forgot to tighten the alternator cable to alternator. cant say if you have the same problem but check this wire from alternator. battery voltage car off, 12.6 or better volts. when running you should have at least 14-14.2 or better at battery if alternator is ok. good-day !
The battery light coming on means the charging system cannot manage the demand on the system - i.e weak battery, defective alternator, bad regulator... Changing parts doesn't necessarily mean the replacements are working. Measure the voltage on the battery with the car running, you should see 13.7 to 15.1 volts. Turn on the headlamps, rear defogger, etc (put the system under load), you should stay in the same range. Assuming all of your electrical connections are good, the symptoms point to the alternator/regulator - these are integrated into one unit.
This is my second oldsmobile i have owned. Now there is two positive connections right above where the battery is make sure they are free of rust and they are tight be careful not to over tighten nuts. Oldsmobile's are terrible for those external positive posts.
sounds like the belt is loose. if it has a tensioner check and or replace it, if not tighten the belt. or the alternator tests ok but is actually not working at low rpm. or the battery is shorted. electricity is tricky
