battery light stays on; alternator and battery replaced and tested and are OK.

it's a brand new battery which has been tested 3 times by different testers and mechanics. I'm not sure how to read the print out, but it reads voltage 12.76U. Further down it reads under charging test: no load 14.15U and loaded 14.26. I don't know if this is the battery reading or the alternator.

Things to check. 1. Check the alternator drive belt condition and belt tension are OK. 2. Make sure your battery post connectors are clean and in good shape,make all shine like never before. 3. Disconnect your battery negative, then loosen the main chassis ground plate just near your wiper motor, clean the 3 bolts and the plate itself well and tighten it back down; then do the same with the engine block main ground connection located on the passenger side engine mount. 4. Replace the battery negative terminal, check you have at least 12 volts across the battery. 5. With the engine at a fast idle, check that you have no less than 13 volts and no more than 15 volts across the battery terminals. 6. If OK, test drive the car to recharge the battery. &.Get back here and let us know your findings.

Thank you so much. I will get hold of a mechanic to look into these areas.

your welcome.
