- 6 VOLT POSITIVE GROUND CRANKING SLOW?
In this video I talk about how important it is to have the correct size cables to get your motor cranking STRONG & FAST.
Converting to 12v is a good idea for some applications, but I keep my 1954 F100 original with the 6 volt positive ground system.
I made "00"cables from scrap cable and copper pipe. Hope this Video helps someone keep their 6v alive and cranking strong.

It's great to see someone young with common sense. may God bless you 🙏 with many blessings
Thank you and God bless. Appreciate the comment.
I have an old 1953 International tractor with a 6 volt and i was haveing this same issue i had replaced the battery cables with standard size cables and for the life of me couldn't figure out why its haveing such a difficult time starting.
This solves the riddle, thank you.
Glad to be of help. Thanks for the comment.
Great video and happy to see you taking the time to explain 6vdc and positive ground for people that are new to vintage cars and trucks and might not know 👏
Good job young fellow! Nobody had issues with 6 volts until about the late 70s. That is when the chain auto parts stores stopped carrying 1 gauge battery cables and 6 volt batteries larger than Group 1. Soon, people started having problems. Old people knew what the problem was, but many young people didn't, and started converting to 12 volts. Also, there are 8 volt batteries. You just have to re-calibrate the regulator if you want to use one of those.
Thank you so much, I love learning about the older stuff. It is pretty simple
Very good video
Thank you. Hope it was helpful
Probably one of the best how to video's that I have seen. Awesome!!
Thank you! God bless 😎
Good video! Ford had 6 volt in trucks until 1955. In 1956 they went to 12 volt.
This video helped me a LOT - thank you! I was completely stumped on why my starter motor was so sluggish after taking it apart, cleaning it, testing 6 volts was reaching it... But yes, it wasn't getting the amps it needed. THANK YOU!
Woooooo!!!! Awesome, glad it helped. 😀
Incredibly great video. Nice to see someone that understands these concepts. ATTA BOY
Thank you. Much Appreciated
Great job
That does seem like it turns over pretty quick for a 6-volt. My 1950 Ford Coupe cranks over really slow it makes it really hard to start. It's only a couple wires I'm going to give that a shot because I'm on my second battery thinking that was it.
Yes the bigger cables bring the 6v to life. I changed out a few batteries before upgrading the cables too. Good luck.
today I learned something ty for it
Glad to help
Very helpful!

Is that a wire running straight from the battery to the ignition coil?
Yes it is. It is the ground wire for the coil. It is a positive ground system. That is how Pertronix said to wire it. I had it temporarily like that. Later I ran the wire to the ground on the block.
Interesting video.
Thank you 😎
Great Video. I have a 52 F1 that has no problem starting when cold but after driving around for awhile and it gets hit, it doesn't want to start. As it would be, my cables are way to small and the heat creating more resistance won't allow the starter to turn until it cools down. Guess I'm moving to larger cables tomorrow. Also, where did you find that Digital volt meter?
Glad to be of help. Let me know if the thicker cables fixed the hot start issue. You at least want 0 or 00 cables. Here is an affiliate link for the volt meter that I use in the 6v set ups.

Just got a 51 Desoto and replaced the battery on it, turns over half as fast as that, if that. I've got other issues as well, mainly ALL the wiring needing replaced since it's pretty well disintegrated. Really not sure how I want to proceed if I want to gut the wiring and change it over, or get a pile of shrink wrap and reline or replace what's showing bare.
Yes. Thicker battery and Chassis ground cables should help it out. In my opinion i would try replacing the wiring if possible. Just take your time. Maybe focus on one circuit at a time. Good luck
Hey I have a 55 f100 6 volt and I can't find wiring diagram anywhere and rats had eaten some of the wires under the hood would you have a pic of how your coil and relay are wired?
Hi Dalton, thanks for checking out the video. I bought a large laminated wiring diagram from www.ClassicCarWiring.com
It is a good thing to have.
I also bought a reprint of the shop manual from amazon. Think it was around $40 but it has tones of info. Hope this helps

On my 6 volt Positive Ground truck I have the (+) post on the coil running to GROUND(+) of the battery or chassis and the (-) post on the coil goes to the IGN post on the ignition switch.
I have a question i have a 1952 ford f2 with a 215 ci engine 6v positive ground im having trouble getting spark i replaced the condencer an the coil but the coil that was in it had the battery an distributor post labeled where the new one has plus an minuses on it wat wire goes to the post
I have mine set up like this. "+" goes to Chassis ground and the "-" goes to the distributor. I am running the pertronix pick up and coil but it is still 6v pos ground

Can you use a 12 volt battery in a 6 volt car
It would physically fit but it would go bad due to the lack of charge. Might cause issues with lights and ignition also running 12v it first. If you want 12v convert the system. If not just get the 6v up to snuff and it will work great.
@@sideyardmechanic idema get spark from it so I'm wondering if 12 volts. Good it women Spark It's a 1959 Austin princess Rolls-Royce
Not sure what your asking. Maybe auto spell messed it up
@@sideyardmechanic yeah I use voice text and I don't reread what I write stupid me I'm not getting no spark it's cranking over but I'm not in any spark I think I might have found the problem a little while in the distributor but I'm not too sure can't find a wiring diagram
@@stevenkasten1149 no worries. Yaw check to make sure your points are clean and set to the right gap. Make sure your connections from the distributor to coil are good and correct
How do I jump start a 6 volt positive ground ?
I personally have not had to do this but I found this online and it seems correct
Disconnect the battery from the donor car, ensure polarity is correct, turn your ignition switch on, place the "hot" jumper lead on the starter motor side of the solenoid, the starter will spin without damaging the 6v system, DO NOT press the starter button.
What I do is connect hot side to hot side, ground side from jumper battery to a dirty bracket in the engine compartment of the car with the dead battery. As soon as the engine fires, disconnect that cable.
@@michaelbenardo5695 Thank you
I got 6 V positive negative vehicle and I can't get no spark I don't know how the wires run to the coil or the distributor I can't wrap my head around it they say it's reverse but
What Year, make and model car are you working on?
@@sideyardmechanic 1959 Austin princess Rolls-Royce limo
Mine turn first push
its ohms law low voltage, higher reastance
Ford went to 12v in 56
Sweet. Thanks for the comment and the view. I knew it was not longer after 54 they went 12v. God Bless
7.2 V maximum on 6.volt
55 is the last year.
