We just changed my valve cover gasket (2.5) today and now i have an exhaust leak and my battery light is on. We checked the voltage on the battery and it is normal. The battery guage is normal. Lights arent flickering. Cant figure it out. Please help

 

Normal voltage at battery is 13.5v to 14.8v engine running, is that what you saw?

12.3v to 12.8v is engine OFF voltage at battery, so if you saw that with engine running then alternator is not working/plugged in

Make sure the 2 or 3 wire connector on alternator is plugged in and tight.

Battery Light on means alternator is a Ground, and is not producing above 12volts

 

Thank you. It is reading the right voltages like you mentioned. Ill look at the alternator today

 

voltage rectifier has likely failed

battery light indicates that the alternator is not producing any amperage

no voltage does not trigger the dash light to illuminate only amperage does

 

Thanks! Battery light hasnt came back on yet so im crossing my fingers it never does

 

you are welcome
