My battery not getting charge. I brought a new battery and alternator some months back so I shouldn't be having this problem. Can you please tell me what's going on and why my battery is not charging?
Do you

Good afternoon,

Can you tell me the voltage at the battery with the engine running with a voltmeter?

Has this been happening the entire time since you replaced the battery and generator? We need to test the charging system at this point because just because you replaced it doesn't mean it is not the issue. The only way to know is to perform the attached test. These have a voltage regulator on them and it may have failed on the new generator.

Is the belt sipping at all?

Run through this test and let me know what you find. Thanks
