No, an alternator will not charge effectively if it is running backwards. Alternators are designed to generate electricity in a specific direction, and reversing the rotation can disrupt the magnetic fields and prevent proper output. Additionally, running an alternator backwards can potentially cause mechanical damage to the unit.
What else can I help you with?

Not likely, but running the engine with a dead battery can damage some alternators. Always fully charge the battery when installing an alternator.
Why new battery and alternator won't hold a charge when car is running?
The alternator does not hold a charge. It charges the battery. If it will not charge the battery then either the alternator is defective, battery is defective, or the connections are corroded or loose. You should read 13.5 to 15.5 volts at the battery with the engine idling. Check it with a DC volt meter. If you get less the alternator is defective. If you get much more the voltage regulator is defective.
How does battery get charge while running the vehicle?
The alternator charges the battery whilst the engine is running via a drive belt that runs off the crankshaft pully
