Re: 6 volt/12 volt jump box
You could build a jumper cable with a solenoid on it and a remote starter button.
That way you can jumpstart from any 12v source available directly to the starter. Using you battery for the ignition (since leadbatteries recover there is usually enough to run ignition after waiting a bit). |

Re: 6 volt/12 volt jump box
Hooked-up the way 51 Merc described passes 12v current ONLY through the starter and to the grounding point. The ONLY place you'll see 12v is the measured differential between the two jumper cables. The radio/lights are essentially in a completely different circuit. The key here is hooking-up to the STARTER side of the solenoid. Same difference as connecting one cable to starter lug, and the other cable to the starter case. You will NOT see 12v anywhere else in the system. DD

I knew you knew better. Sometimes, that second cup of coffee really helps. DD |

Re: 6 volt/12 volt jump box
Y'all ever thought about the everyday 6v/12v conflict that occurred umpteen times a day way back when? Neighbor's '49 Ford battery (6v) is too weak to crank the old flathead over. Since SHE is so good looking (and a really NICE person, too), I decide to give her a push with my new '55 Chevy (12v). When both bumpers line-up and touch, we now have a COMMON ground between 6v POS ground system and a 12V NEG ground system. Even with this common ground, the fact remains that electrically, you have two separate circuits that have no detrimental effect on each other. DD

Re: 6 volt/12 volt jump box
Thanks for the help/advice. Gave up on the idea and picked up a 6v/12v charger/maintainer at AutoZone today (Schumaker).
Thanks again. Paul in CT |

Gave up on the original plan. I picked up a 6v/12v battery charger/maintainer at AutoZone today (Schumaker).
Thanks again for the help and advice. Paul in CT |
