Hi there
You may want to remove and clean all of the cables that are involved with this and make sure that there is no shorts is the wiring and also check the belt and make sure that it is tight and see if there is a master fuse for the charging system under the hood also check to see if the solinoid is working properly you can also take it to a autozone and they can do a free diagnostics of the system

Alternator put in and the car won't start and dead new battery'

I am taking it you have a new battery. You put on a alternator. Now you need to charge the battery until it is fully charged. That way the car will run for a while before it stalls from undervoltage. With the battery charged check the voltage at the battery. It should be 12 to 13 volts. Now start the car and check the voltage it should be up to almost 14 volts. If that is good check with lights and heater blower on should be at least 13.5 volts. If the voltage does not increase you either have a bad alternator or it is not getting excited by the ignition switch on the vehicle. So you should find the wire that energizes the alternator and turn the key on it should have 12 volts on it. Hope all this helps. please rate my answer so I get points.

I buy a new battery n alternator n starter n mi battery is not chargin what should do next?

The first thing to do is check all of your grounds. You should have solid ground points from the battery to the frame, frame to engine and engine to body. If a ground is bad, it can cause a problem with no charge or even overcharging. Ensure that the alternator is actually providing power using a voltmeter. I've seen rebuilt alternators bad right out of the box.

Battery wont hold a charge. it takes a charge, i drove it around the block, kept it running in park and when i turned it off it wouldn't turn back on.

First, it can damage your alternator to try to charge a dead battery by just driving or running the car. The alternator is designed to maintain the state of charge already in a battery.
Old (pre mid 60's cars with generators could do that).
Have your battery charged and tested. if it checks out, then have the charging system in the car tested. On most newer Jeeps, the regulator is not in the alternator it is part of the computer. If the alternator checks as good but it is not charging, that may be why.
Hopefully you just need a new battery.

How do you determine between alternator and battery? 2003 jeep liberty frequently won"t start - no radio either, but the lights and windshield wipers do. starts right up when i get it jumped...even after...

the alternator charges the battery so if that happens then your alternator is bad but if you jump it and it works for sometime then i guess ur battery is bad so change the battery

77 CJ5 hot alternator after being shut off for hours. Battery drained. Amp meter pegged.

The diodes in the alternator and/or regulator are most likely to be the problem. Remove the alternator and have it tested at your local parts house. This is a free service.
Good luck..i hope this helps.

Could be an open connection in the line feeding the battery. Is there a fusible link inline? If so check the fuse or the line itself. Run on Ohm test from alternator to battery; this will tell you if the circuit is good. Sometimes it's as simple as a corroded or loose connection.
