Hey Jeff. Never assume that "new" alternator is good, but lets assume it is.The actuator wire that goes into the field of the alternator HAS to be hot with the key in run position. (both wires will be). If not, it wont charge. If those two are hot with the key on, the alternator is bad.

A sitting battery has about 12.5 volts. A running engine should be around 14 volts. If less than 13 alternator is not working.

In my area Autozone, Kragen & Pep Boys will check alternator for free.

If alternator is working and battery still ends up dead then something is draining battery when engine off. This takes more advanced troubleshooting.
Remove all fuses. Put ammeter in series with battery add fuses one at a time individually until ammeter shows a circuit drawing more than one amp. (clocks and computers will use very little power)

1996 cadillac eldorado not charging

You most likely have a grounding problem either on the bar in front of the battery that holds the radiator or the ground at the back of the engine (actually between engine and trans). You can see that ground without removing any covers. This is a very common problem as the wires tend to break inside the insulation due to vibration and age. Open hood, look just right of center and half way down the engine-transmission link. That's your problem, most likely. Remove neg batt. cable before you unbolt, clean and check black grounding wires.

I suppose the belt could be slipping when it is warmed up.
Have you checked the output of the alternator to make sure there are no weak connections between the alternator and the battery ?

My volts keep dropping an it sputters and backfires batt is good and alternator is new

Please check if the rectifier/regulator unit has failed or is weak.
This can create fault in the charging system and cause fault in the ignition.Check the battery ground , clean terminals.
So check this out and check the timing ofthe engine.

My 1993 cadillac eldorado is cranking slow and i just change the alternator

If the battery is fully charged but the starter is slow, the starter may have an internal short or may just be worn out. Make sure your battery is fully charged and the battery terminals are clean and tight though before buying a new starter.

My 1996 cadillac eldorado says battery no charge now hard to turn but it cranks right up

Most likely you need a new battery but do this first. Remove the battery ground connection and the positive connection. Clean them with soda water(coke is sticky but all sodas will work). Scrape or sand the inside of the cable connectors and the outside of the battery posts till they are shiny. A low battery light usually means it is not fully charged or taking a charge optimally but effective troubleshooting the battery and starting system starts with clean,secure connections and a fully charged battery. If your battery has electrolyte filling caps undo them and check the level. If they need topping off use distilled water only. Charge the battery with a car battery charger. It should read about 13.4 Volts under no load. Check and clean the battery negative cable connection to the block and the positive connection to the starter solenoid. Check for good connections to the charging output from the alternator. Inspect all wires for kinks, cracking, shorts, ect. A good once over will reveal probem wiring. Reinstall the battery and cables. Giv'er a crank and see if that is not stronger. Drive it for an hour or so and crank it again. Any noticable degradation in cranking power means you have a bad battery, alternator, diode pack if applicable, voltage reguator, or any combination of the three. Take your alternator and battery to your auto parts dealer. They will usually test them for free. Aslo, starters can wear after time but this is most likely not your problem based on the symptoms.
