    Jerry,
    Well, I wasn't around anything like that, but, I do know the 2 big 12 volt batteries to total a24 volt system, if shorted, was really a big blow up. We also had to mix our own acid for them. Hahaha.

    Most aircraft were 24-28 volt-Caravell were 124 dc--------12 large heavy duty 12v wireed in doubles for charging from the Hobart then big knife switch that swapped them to series for the 12x12-------------

    possible drains???????? Points closed causing condensor charge( would of caused a spark on disconnect), sticky brake pedal, starter solenoid, and/or bendix--------radio, gererator/ voltage regulator, glove compartment light,dash lights, turn signal flasher--------

    How long did the car sit since you last drove it? If you have a digital multi meter, hook it up in series with the battery cable to measure the amperage draw with everything turned off. It should not be over 25 milliamps.

    ..... and if it IS over 25MA you can pull fuses one at a time, watching the meter to see when it drops, to find which circuit is feeding the draw/drain while it's sitting idle, and then go through that one circuit to find the culprit. A simple process of elimination.

    Points closed would not cause a drain unless ignition was left on.

    I posted this link to help on checking things. Why doesn't it get clicked on to see the info ?

    (Points closed would not cause a drain unless ignition was left on.)
    That is correct...

    Thanks for all the input. Let me try to respond to all of them.

    The car was last driven a week ago. As far as I can tell nothing was left on. No signs of any lights after recharging the battery. Radio was off. It has a Pertronix ignition so no points.

    The battery is a Duracell that's about 18 months old. I'll get it tested.

    I did follow the link Denny posted. I need to get a better meter to run the tests.

    Firebird--Points closed draw would/could mean bad ignition switch and/or starter solenoid-------would cause a spark because of the condensor charge/coil secondary windings

    For the price and what it will be used for this one is hard to beat.

    i use a disconnect. helps quite a bit but a battery will go dead sitting on a bench. if not regularly charged it will sulfate and be junk. in winter storage take it out and trickle charge all winter .
