I recently had problems dead batteries. The number one odd one was the glo plug timer staying on. That put a drain on the car running for an hour or two during the day. Three good alternators and only 12.4 volts will not keep it charged. The other was the power antenna. The mast broke and the antenna motor wanted to go down and would not shut off while parked.

Just two wierd problems you would not really think of checking otherwise.
