First check alt At The Back of Alt Big Red Wire Were hooks to Post (stud) Do you have voltage ?? How Much??
What Voltage do you have at same Place with Engine Running ??
Now At wires Were they plug into Alt ,Top. Wires in White Plastic Clip, Do You Have Powe With Key On ?? How Much Voltage??
Jump across the 2 in the clip (with Engine Running)ONLY TEMPORARY!! Do You Have Voltage at Battery ?? How Much??
If Over 13volts With Clip On (Jumped) You Need A Internal Voltage Regulator ..
Is Batt Light On on Dash ??? Theres A Lot Of Testing You Can Do !!! And I will Need More Infomation to Keep Going ... These are just some Possible Problems No Way In Depth ...
Could Be a Number of things Or May be Just as Simple As a Blown Fuse, Dirty Batt Cables ETC etc etc I Hope It Puts You On The Right track !!!!!!!!!!

clean battery terminals ,bring battery to be tested after charging, after reinstalling battery run car and test alternator output it should be a minimum of 13-14volts if it is under 13 replace alternator , use a voltmeter set on 12 volt 10 amp dc to check the wire to check is located on the back of the alternator covered with a rubber grommet of course hold negative wirw on volt meter to ground and touch red wire to big terminal on back of alternator while car is running should have 14 volts or at least 13 volts
SOURCE: dodge neon 2002. My alternator is not charging,
wires run direct to alternator from battery ,test big lead for a permanant 12v supplyon the back of the alternator if you have one then the problem is either the brushes worn out or the commutator worn through.or the regulator either way its a recon unit as parts are not sold seperate anymore as not many dealer mechanics know how to repair anything and the spares shops make more profit on a unit than parts so they do not sell spares to stop people like me and you from doing our own repairs

Thank everyone. The problem is fixed. It was the fusible link wire. I would have never found it, for all the test readings were all good. Until i decided to to test all the alternator wires and when I pulled the fusible link wire, it broke. It didn't even show signs of burned or melted rubber insolater. I was lucky to ahve found it and didn't have to splice too far into the wires.
It only tooked me three months to find the problem, and I did it without a computer, OBD II tester, I turned in to our local dodge dealer, and hoping they would find the problem. Instead, I paid $98.00, for incomplete test results, cause they told me that my alternator, battery, and engine wiring harness needed to be replace. I am looking at spending close to $2500 or more. They told me the battery was alternator and battery was bad, They're both new. They siad the wiring harness needed to be replace because the wire to the starter wasn't the original, another words RIG. So I told them, that I can't afford the repairs, so I just pay the $98.00 and get my car. I can't see myself paying that much knowing that I can do the same. If I start changing everything that has to do with the charging system on my neon, I will fix the problem. Which what I did, with the help of the internet. I fix my charging problem, and it only cost me under $20.00. Thank you again.
