Charging voltage should be around 14 volts or more for battery to be properly charged. If significantly below that the alternator is not working properly.

Replace the alternator. Once the battery dies, the alternator should still have a little bit of power left in it, if your car isn't starting after it's been jumped, chances are that the alternator is shorted out. Replace the alternator, and also recharge your battery. Check your battery terminals for signs of corrosion, and clean it off with a scrubbie and a mix of water and baking soda.

You are on the right track...the battery will only allow the car to run a few minutes if the alternator is not re-charging the battery while running...most parts stores will test your alternator for free...on your Caddy, the alternator is held on by three mounting bolts...be sure to disconnect your battery before working around the alternator. Inspect your alternator belt...(serpentine) may also need replaced...some used to call this belt the 100,000 mile belt...I recommend changing mush sooner...check for cracks and worn edges etc. Hope this helps.

was the new alternator a re-manufactured one,(they have been known to be faulty)

start the car up then take the neg battery terminal off ,if engine keeps running its a battery needs changing ,if it stops renew the alternator

Could be your alternator. If you can get it started again. Try to have the alternator checked out.

I had the same problem. trying to save money i took it to several auto places who thought they could fix it..... after a lot of money and my 800.00 after market alarm was taken off i had it took to the dealer . They fix it in two hours they put in new switch and key haven't had any problems sence.

CHECK THE FUSE OF THE ALTERNATOR OR CHECK IF THE ALTERNATOR IS CHARGING

look for fuse for alternator and the DRL.
