Dear Packard0:

If the car is going to sit, disconnect the battery.

You never know what might happen to all those live wires floating around. Disconnecting ground is safer because you can't short the wrench against anything.

Also, there may be carbon tracks in things like the ignition switch that will trickle away charge.

Still another is the clock. If the battery runs down, the clock starts using higher amperage.

I've known people who let cars sit with batteries connected for ages with no ill effects. Usually, the clocks didn't work. But one case comes to mind of someone we all know who had a fire start in one of his cars. After that he had me putting disconnect switches on everything he owned.

The only time I didn't recommend power disconnect was in cases where the owner would say something obnoxious like "Is there is some reason to disconnect the battery? I suppose I should take the car to somebody who can fix it." blah, blah, blah. One time I was told that anything can be fixed given enough money is thrown at the problem. My response was - "Then build a time machine."
