Liz1215 Posted July 2, 2022 Report Share Posted July 2, 2022 Hello, Does anyone have know what could possibly keep my battery light on? I purchased and installed a new alternator and before install it tested good, I also installed a new battery, cleaned and tightened my battery cables before install. Swapped my pcm fuse for a blower fuse just to test if that was the issue, and the battery light is still on. I’m at a loss and don’t know what else to try. thanks for your help in advanced.

1004ron Posted July 2, 2022 Report Share Posted July 2, 2022 Welcome. When you say "new" alternator, was it a reconditioned one, and where did you buy it? Do you have a multimeter do do a few checks that we could suggest? Quote Link to comment Share on other sites More sharing options...
Liz1215 Posted July 2, 2022 Author Report Share Posted July 2, 2022 (edited) I bought a reman alternator from o’reilly’s but had them rest the alternator before I left the store and it tested good, the battery is also new. I don’t have a multimeter I could purchase one though? Edited July 2, 2022 by Liz1215 Quote Link to comment Share on other sites More sharing options...

On this forum and another one I frequent there's been reports such as yours with rebuilt alternators, and without doing any diagnostics, the alternator would be my guess as to what's wrong. Here's one of many examples: https://www.kia-forums.com/threads/2005-kia-sedona-lx-multiple-alternators-and-batteries-replaced.221729/#post-1308481 Quote Link to comment Share on other sites More sharing options...

Yes, and who knows what criteria they use for testing. You're better off having an auto-elec shop rebuild your original one, or get a good identical one from a wreckers yard, or a new OEM alternator. Try a search for radiator cooling fan assemblies - its known here that all third-party fan controllers don't work, reasons unknown. Quote Link to comment Share on other sites More sharing options...
DILLARD000 Posted July 2, 2022 Report Share Posted July 2, 2022 (edited) Yes, you need a basic MultiMeter\VoltMeter. An OBD2 Scanner that can read+reset TroubleCodes is also recommended. Engine shutdown, Battery should read approx 12.8v (newer) ~ 12.3v (older, time to consider a new battery). Engine running after cold start, Battery should read approx 14.0~14.5v = charging. Engine running fully warmed up, Battery should read approx 13.5~14.0v = charged. Edited July 2, 2022 by DILLARD000 Quote Link to comment Share on other sites More sharing options...

That schematic is why I don't believe that the auto accessory shops have the ability to test these alternators,. The old type that had just two connections they could reliably bench test, but not the latest ones that have data communication with the vehicles body control module.
