Well I am stumped. The two batteries in the spots closest to the frame continue to go dead. The alternator is charging correctly (14.4, 27.7) on both ports, and the batteries take a charge off of a charger perfect. But they go dead. When reading voltages on the batteries while engine is running, I see 27.7 across the 24V side, but only 13 on the 12V side. I don't completely understand the set up in these trucks as far as the hybrid 12/24 so possibly I'm reading things wrong?
I verified the battery connections per the diagram on the battery cover (A0, no shut off relay) but it still goes dead every night. Not sure if its just bad luck and I have 2 bad batteries, or?????
Thoughts?
