Hello everybody,
I have a big problem with an 5.7 etorque system.
My customer had a bad bearing on the 48v alternator, the bad bearing make a lot of noise but he decided to drive the truck 6 months like this... after that, the alternator were not able to charge the 48v and so the 12v... We had changed the 2 bearings, the interior of the alternator seems to be good with no damage but ??? we had replaced the alternator but the 12v battery won't charge.
We live in Belgium, there's no Ram garage able to fix that, no real aftersale service and no technician. A new alternator is about 4000$ here with 4 month of delay... no one can test 48v alternator to say if the alternator is ok (even if a lot of brand has the same system of 48v mild hybrid but these days, they only replace part...not repair)
So I would like to know, if the 48v batteries are completely empty, is the alternator able to charge them ? because if the 48v are empty, the 12v never charge...
I really would like to test the alternator to eliminate this factor but I'm not able to do this ?? is this possible to see if the alternator charge the 48v battery with a scan tools (I have Alfa obd, Witech but only for -18 Ram) ?
Does anybody already had the same problem...
Thank you for your help
