JumpStart 6 volt with a 12 volt - 02/09/04 05:47 AM
I received a 12 volt portable battery JumpStarter for my birthday last week. Cool.... but....
In past years, I've used a 12v car to start my 1931 engines.... but have always been a bit afraid of what it might have done to my gauges.. but after all these years, they're going strong and 12 v really turns these babies over in a hurry!
So, here's my question -- With a 12 volt supply, what could a guy add in series in order to step it down to 6 volts? Somehow adding a big honking wire-wound resistor seems to be the right thing to do... but then how do you prevent it from getting hot, etc?? Wouldn't this be a good doo-hickey to keep around?? <img border="0" alt="[twix]" title="" src="graemlins/twix.gif" />
Any ideas for an easy way to use 12 volts to start a 6 volt system? :confused:
