Default Re: Jumping a 6 volt battery

The original question regards jumping a 6 volt battery with a 12 volt battery.

I have done that with my 1933 Chev. This was a negative ground system and when I connected the two together it was a very brief connection. Its somewhat risky because the jumper cables will act as a resister that changes the 12 volts to 6 volts.

I did the "jump" when I was 18 years old and was "indestructible". Today I would use a battery charger made for 6 volts.
