After replacing Alternator,the battery indicator light Comes ON dash?

If you need dis-assembly or replacement instructions for any other auto/car part, or you want to ask question related to your car/truck jeep problem then please leave the comment with your details, so I can provide you the required instructions and solutions.


The reason the battery light is on is that the charging system voltage is below the battery voltage, this means the charging system is not working correctly, since you already replaced the Alternator for I assume the same problem, unless you got a defective rebuilt the charging system problem is not the Alternator but lies elsewhere in the electrical system. Use a volt meter and check the voltage at the battery cables with the engine running at high idle (at least 1000 RPM) the voltage should be at least 13.4 to about 14.2 Volts DC. This is also most likely the cause of the light that is on dash.But if All checked ok,then yes it can be faulty alternator,try with another alternator and confirm.------------
This details will help.Thanks.
