When a new alternator is installed, does it charge for a bit and then stop working?

If so, how long does it charge for?

about 35min

Thank you for that information.

Have you had the battery load tested?

Ask Your Own Nissan Question
Customer reply replied 4 months ago
no

I would certainly do that first as a faulty battery can prevent the alternator from charging.

Also, have you checked the inputs to the back of the alternator when this no charge condition occurs?

The alternator check bad and I have had them replaced 4 times by PepBoys

Ok, then if they all check out bad, that means you're getting low-quality alternators. It is as simple as that.

will a battery cause a alternator to go bad or time

YES, it is possible. That is why you should get it load tested.
