After sitting for more than 2 days, my battery is completely dead in my 1998 Ram 5.2 5-speed. New battery in January of 20. Had a diagnostic performed at place of purchase and I was told alternator and battery were fine. Anyone have an idea?

 

Battery Drain

 

If you don't find anything obvious, have a look at the seat belt module under the center seat.

 

15.4V at the alternator with the com wire from the meter touching the battery ground . And 15volts dead on at both batteries so I'm like 2 volts 2 high If 13.3 is ideal. What are yall thinking??

Thanks again yall

 

I think 14.7 is considered 'ideal'..... Anything over that is considered 'bad' for the battery....
