I had the Van basically stall at idle while in the parking lot. Had to be towed to Ram and they diagnosed a failed Alternator. My van has a second generator alternator for the Volta Pure 3. I only had 3500 miles on it when it seized up. I found it strange that a brand new alternator would seize. The Ram alternator was the one that seized. Now after the repair, I am getting a very loud squealing sound when it cold and seems to go away at highway speeds. Only occurs when the Volta alternator is charging the system. When the Volta is off, no squeal. I assume there is an auto tensioner on the system and the belt should fine as it's brand new. Could a bad tensioner have caused too much tension on the original alternator and be the culprit for the squeal? Could the belt be too loose and when the 2nd alternator kicks in it's simply slipping? How could it be too loose assuming it has a tensioner. I do hear a chirping sound occasionally when it's warm, but the screech is gone after driving a while. Any suggestions or thoughts? It's still under warranty, but time is closing in. Thanks! UPDATE: Here is the sound if you turn up the volume. New video by Deas Nealy
