Bad connectins at battery? Clean connections. Possible loose battery cables on starter or engine block? Clean and tighten cables. If no help, possible bad battery cable/cables. Test cables and replace as necessary. Depending on what type of car, also investigate starter cylinoid. Hope that helps.
Most likely, your starter isn't the problem. You may have a bad alternator. Usually when your battery doesn't recharge properly it's an issue with the alternator. Have a mechanic inspect the alternator if you're not comfortable doing it yourself. If it is an issue with the alternator, it's a pretty cheap fix.
So, what you're saying is that your car isn't charging the battery since you changed the starter... is that right. If so, my guess is that you accidently left off or possibly even burned out the fusible link between the battery cable and the alternator. If this is the case, that's why it won't charge. So, make sure yoiu've still got a connection between the wire between your battery cable at the starter and the alternator.

Check spark plug wires, and voltage on the distrubutor.
If the starter is "clicking" then check the battery to make sure that is has enough juice to turn the starter. If the battery is good. It could be your starter solenoid is bad. Most of these are built into the starter nowadays. You will have to have the starter changed. I am betting on the battery especially if it is older. Another culprit could be your alternator failing to charge your battery.
it may be the starter going out doing it . it will kill the alternator if it keeps going . I know i had it happen to my 96 olds replaced the alt still didnt start and the starter fixed it
Check the starter
Check your alternator and your connections form the battery to the Starter. You may just have a bad connection If that does not work, your solenoid on your starter has gone bad, a new solenoid or starter may be needed. Check the start switch on the clutch pedal if so equiped.
Did you replace the battery? I am trying to determine why you changed out the alternator which charges the battery, and the starter which only starts the car. The 2 are only related through the battery. One system does not rely on the other. As you drive the alternator puts a charge out to recharge and maintain your battery. Your starter only engages when you turn the key to start the car and this draws a lot of voltage from your battery. Try to explain in better detail: Like the car will try to start, it will start but won't keep running or the car won't even turn over, or I am getting a clicking sound. The better you describe the situation the easier it is to get you pointed in the right direction
its the baterry
Your alternator is not charging the battery like it's suppossed to or the battery cables might be corroded and may need to be changed or cleaned, but the good news is autozone can recharge your new battery back up for free. Also make sure after you change the alternator and clean the battery cables and put the battery back in have the guy at auto zone test the new alternator before you buy it to make sure it works properly.
Since you changed your battery and starter I'm assuming you are getting fuel and spark is your problem. You should check your starter relay, the wires from the relay to your starter, the wires from your battery to the relay, the wires from your locking cylinder to the relay, and your locking cylinder. You might also check your alternator. You can take it to a parts store to have it bench tested for free.
Remove the starter and haeit checked at auto parts for amp draw Check the alternator to see if it is keeping the battery charged Check engine ignition timing may be too far advanced
