How was the battery checked? Why was the alternator replaced?

Roy

Checked at advance and changed alternator because battery light come on and my husband took terminal iff battery to test alternator and it was bad so we bought a new one know it wont hold charge

Taking the battery cable off while running does nothing but damage other components. Never a test for alternator as it needs 12 volts to work. Removing the cable shuts everything off

Roy

Oh ok that way he was told to check it. We took both the battery and the alternator back off car and advance tested them said they was good but when put back on car still wont hold car any ideals I thought maybe it starter relay

Check the voltage at the battery with the motor running. It sounds like you have a bad battery

Roy
