Just replaced the starter and now my battery isn't charging and the battery is new but the alternator was good till the new starter now the alternator light is on.
I would check the altenator again. if you didnt disconnect the battery and a spark shot off while installing the new starter it could have decharged the spool on the inside of the altenator to where the spool no longer charges. if you have the altenator checked for consistant charging and it comes up good check the relay for the altenator it most like will have messed up the relay. to make a long solution short check the relay for the altenator it will be in the relay box under the hood.

If a good battery is losing charge overnight then it is probably being drained by something left on! The usual areas to look at would be the boot light or glovebox light, check these or anything that might be staying on when the ignition is turned off!
the starter only turns the motor when the key is turned. the alternator charges the car when its running. if its dead you left something on to kill the battery. charge the battery. then get the charging system tested. advance autozone and I am sure other parts store can check the car for free
Have you replaced the voltage regulator? Unless you have changed the charging system and eliminated it, the alternator does not have a built-in voltage regulator like the newer ones do. Be blessed.
it sounds like you have blown fuse to the Alternator.. I don't know what car you are talking about but they charging systems vary.. But if alternator isn't getting all the power it needs it won't charge. this should be checked.
your battery needs replacement, it may show 12 volts but the amps aren't being charged enough,, if you take the battery and have it load tested,, you will see that one or more of the cells isn't charging correctly,, if the battery checks out ok, then with the truck running, place test leads on the pos and neg battery terminals,, you should be seeing a reading of 13.5-14.5 volts,, if not your alternator is bad, if you do,, its the battery for sure , make sure also that all the battery connections are clean and tight ,, dirty or loose connections will prevent good charging
A bad voltage regulator could cause the problem. Assuming the alternator is working correctly. Jump the vehicle with the battery disconnected and then disconnect the jumper cables. If the vehicle dies your voltage regulator or Alternator are bad, some vehicle have separate regulators from the alternator, if it continues to run the alternator is good but the voltage regulator is probably the cause.
Does it crank well and all that but with no spark or is the battery just dead? If the battery is dead, it either won't charge while alternator is spinning or the alternator doesn't charge well enough to keep the battery charged well. If it jumps and runs indefinitely, battery is done. If it jumps and dies, alternator is done. If battery and alternator are fine, and you have no spark, you may need a new coil, new spark plug wires if they are worn out and too resistant, pick up coil inside of distributor, or you may have some other ignition system issue.
Most times when an alternator fails, it starts charging less and less till the car won't keep running or it won't start the next time. If the alternator hasn't failed, the battery needs replacing. If your battery is 5 or more years old this is a very good possibility. If your alternator failed and you have killed your battery many times before replace them both. Each time you drain a battery to dead you lose about 10% of its current capacity.
If the battery is fine and engine will not turn, starter may need replacing. Hope I helped.
It appears that the alternator is still not charging the battery.Charge the battery up,and refire the truck.Check voltage with a voltmeter,directly off the back of the alternator.Most all alternators of your year model have the voltage regulator built into the alternator.If the alternator isn't producing any voltage,then it is bad,even if it is new.I have had defective new parts before.
