I recently changed my alternator on my car and thought that was my problem, but I started the car it just drained the battery. So someone said change the ignition switch so did that and still have the same problem it drains the battery. Recap; new battery, new alternator and new ignition switch. But still no charge can someone please help?

Good afternoon,

Do you have a voltmeter to do some checks?

You need to see the voltage at the battery with the engine running.

I attached a wire diagram for you to view. check the three fuses listed for power on both sides with the key in the on position.
