Does the battery warning light turn on when you turn the ignition switch to "run"? If it does, does it turn off when the engine is running? Do you have a digital voltmeter and know how to use it?

Engine Light on means a fault has been detected by the engine management system. Did you check for trouble codes?

Why do you think it is the alternator that is not charging?
