BigKev - Great minds think alike. What you did for 4 batteries, I did for the Packard. Your circuit would certainly work in the 6v car (reverse the polarity of course).

I used mine today with my GPS - just to test the accuracy of the speedometer (which by the way reads about 1-2 mph faster than actual speed)
