It's a 12 volt '56 1/2 ton, with an alternator. The drain was happening before the alternator installation! I really appreciate all of these tips, I will spend some time with the truck in the next few days and chase this down.
I knew there had to be a way to do this, going to the best site for ol' trucks on the internet and asking a combined 10,000 years of experience was the way to go. Thanks again.
Joker, how was the clock problem solved? Ed
