A month ago I replace the heads from the headlights and bulbs,
the bought the blue color head with three black wires,
then after a week and a half the battery light started turning on
then I started having problems with battery.
I went to Autozone and they told me it was the alternator.
Yesterday I bought a new alternator and battery,
but the battery light keep turning on.
Help!

Good morning my name is Roy and I will assist.

Do you have a volt meter to do some tests?

Check the voltage at the battery with the engine running and see what voltage you find. It should be 14 to 14.5 volts.
