Geez, what a deal!! I write the above post and go to make a run in my '48 after sitting for 6 hours. Doesn't start and the battery goes down trying!!!! I should have kept my mouth shut.
12 volt seems like a mighty fine idea.
(I drive only three miles to work so I think there hasn't been enough charging time in the cold, cold weather. I think we'll look for a place out of town.)
