    Somebody needs to make me some so when my battery dies in public I can get a jump from a 12 volt car. :confused:

    I guess you don't understand how electricity works....
     
  3. if your ford is the problem use the jumper to the starter side and just crank with the 12 volts
    or frind someon who knows how and convert to 12 volts in 1963 6 volts was obsolete then , get with the new age elicteric program 12 volts

    I am not sure why, but I like the original 6 volt system. It works fine. It just ****s when the battery dies.

    Now that's thinking there! I'll give it a try.

    Why can't you jump your 6v system with 12v? I've done it with my 53 Chevy before I converted to 12v. Never a problem.

    People do it every day. just remember that your Ford is Negative ground.

    Better yet buy yourself a jumper box and keep it in the trunk and you don't have to depend on someone else. The 12V will just spin it a bit faster and shouldn't cause any problems if you don't have anything turned on.

    Or fix the problem that is causing the battery to go down and don't worry about it after that.
    Or park on a slope if it is a stick so you can coast it and dump the clutch to start it.

    Yep, me too. Just crank it up and remove the cables. Don't leave 'em on the battery for longer that it takes to get the engine started.

    Same here. Always was having to jump my clapped-out old '59 beetle I drove as a kid.

    Leave the cables on there too long and you'll let out all the smoke.

    It could be done, but you'd need one hell of a big resistor to place inline.

    Better to find out why your battery dies so much, especially while out driving around.

    6V troubles are frequently just excess resistance from dirt and rust or sometimes a bad part like a fried solenoid. Any voltage drop with only 6 to start with gets bad in a hurry.
    Make sure you have heavy gauge cables, not common parts rack ones meant for 12 volts.
    Clean both ends of all cables, wire brush terminals and whatever they attach to.
    Add a dedicated extra fround cable from engine to where bat ground bolts to car.
    If still slow, jump from battery right to starter and see if cranking speeds up...if it does, something like solenoid is adding in resistance.
    With all well, 6V works fine as long as you stay south of Buffalo.

    Well the battery didn't die really. The engine flooded due to a float bowl problem and the battery ran down while I tried starting it. I was afraid of frying my fuel level indication with 12 volts since I can't turn it off. Thanks Slick Willy, without me...it's just awe so!

    On a stock '55, I think I would only worry about turning off the radio for short term 12.

    If you stilll have the original gauges, then you probably have the original instrument voltage regulator. So you probably will be ok as far as the gauges with 12V booster.

    There are ways of building a switch mode voltage reducer that would at least supply 20-40 amps of charging current. You could hook that up to the booster source and allow the battery to take some charge, then disconnect the voltage reducer and try to start.

    How about a carb rebuild and a new battery?

    UMMMMM..... Just convert over to 12 volts, makes it real easy.

    That would be Positive Ground.

    Another option for the 6v crowd is to buy a 6v gear reduction starter. They dramatically reduce current draw for starting, and therefore put a lot less strain on the battery and recharging system.

    it actually can be done if the jumper cables from the car giving the boost attached to two six volt batteries in series with two leads coming off one of the batteries +- to the car being jumped. would be a real pain in the **** to carry around.:D

    On the 6v car I own I have learned one valuable lesson. Most 6v batteries sold today ****. No, they really really ****.

    Meanwhile, Optimas are lovely things. Buy a 6v Optima, theyre boxy but theyre good.

    I seen the 12v to 6v cables at o reily today. They are between the blinker fluid and muffler bearings. Ask the parts guy for the metric left handed screwdriver socket set and he will lead you right to them. Good luck.
     
  27. You can do it, just make sure to put the cables on right before you jump and take them off right after the engine fires- did it for years with a '30 Packard with no adverse effects.

    what a fine bunch of ***es. the old hamb is back. we should try to be nicer to new people that are here to learn. the guy didnt ask about his 85 t bird with trans. problems , or how to build a 4 door buick g***er. rant over

    run 2 six volt batteries,run the accessories on six,the starter on 12 and a generator rewound to put out 12v.then a 12 volt boost is doable.
    carry a spare six volt?and three cables?
