Batteries not staying charged

Asked by Jared Mar 24, 2017 at 11:17 AM about the 2001 Ford F-250 Super Duty XLT Extended Cab LB

Question type: Maintenance & Repair

Wednesday I was having issues starting my truck.
Took the alternator off and took both batteries to
be tested at Auto Zone. Batteries were fine
Alternator wasn't putting out the right volts maybe
8v. I bought a duralast gold they had in stock and
installed it. After install truck started right up no
issue. Drove it around for about 30 minutes and it
ran fine meter on the dash read over 16volt for the
batteries.  Next day and today the truck hasn't had
any battery power and is barely starting. What
would be the cause of this?

Sounds like you may have a defective alt ,should be putting out 13.8 14 volts ,while sngine is running ,16 volts is to high ,hope this help you ,when you install a new alt make sure the battery's are fully charged, not saying they weren't but sometimes people try to charge a low battery with the new alt ,this makes the alt over work ,in some cases burnes them out ,not always but have seen this happen Good luck scott
