6V vs. 12V vs. Electronic Ignition

Postby Bill Hudson » Mon Jan 18, 2016 6:00 pm

I have long been a member of the "A properly tuned 6V system will start without problems" club. I still believe that is true. This summer I converted my snow plow Cub to 12V with the Pertronix electronic ignition. The reason for the change was to allow me to add (still to be completed) a flasher for safety reasons while plowing in limited light conditions.

At the time of the conversion I marveled at the change in ease of starting. That is still the case even in cold conditions. It was 16 degrees F this morning when I went to plow snow. The Cub started without hesitation, instantly! I'm sold! What a difference!

I realize that this particular topic has beaten to death on numerous occasions, however, I wanted to note my experience and admit that minds can be changed.

I've had a 6v Pertronix ignition for years and it is amazing. New battery, cables, etc also does wonders.

There are 6v flasher systems out there. Common in antique auto circles. OF COURSE 12v stuff is easier to find and a system-wide conversion to 12v would be easier (and probably cheaper) than a separate 6 to 12 dc to dc converter and circuit. I personally don't take any small non seatbelted/rollbared tractors on the road or out at night. Be safe!

Do you have any issues with the 6V petronix?

The 6 volt system started fine today, 14 degrees and the 6 volt flasher works well (earlier photo, no action shots available).

I added this back in December, just before Christmas, when it was still in the 40's.

I had to pay more for the vibration dampener than I did for the hour meter.

The 6V vs. 12V debate is purely academic. If a 6 volt system is up to snuff, it works well and is completely reliable. If a 12 volt system is up to snuff, it as well is also completely reliable. It just comes down to what do you want to do?

I purchased the 6 volt Pertronix electronic ignition but then hesitated to put it in because of some comments about jump starts and when it fails it fails - not a slow death. Two of my three 6 volters are reliable starts (one mag & one battery/coil). A new acquisition, a '57, may get it to try.


I have been thinking about a 12 volt circuit just for LED lights. $17 dc to dc step up behind the dash

agreed, there is no comparison of points to electronic ignition, whether 6 v or 12 v.
I installed pertronix on my 51 6 volt positive ground Plymouth, the car has never ran better, started easier, all around a smoother running flathead with the pertronix module and matching coil. I'm all for original, but crap, when its installed you cant see it under the cap so who is to know?

going from points system to an electronic ignition is like being a caveman and hunting with a pointed stick and somebody hands you a rifle....

Bill, I have a 67 cub loboy, you wouldnt happen to have the part number for the 12v module that fits our type distributor?

My 574 has that silly ign no-points thingy in it and 50 wires coming from it going to who knows where!---When the engine goes back the points and hardware go in.---had to pull the dist. out and stuff it under a cover and leave it hooked up to the tractor` when I took the engine out so I imagine it's junk anyway. thanks; sonny

Sonny if you did not have that silly one with 50 wires, you could have one with only 2 wires :roll:

thanks!
ordered mine and the matching coil from amazon prime last night. probably get another 500 HP with the install, mebbee ride wheelies now :-)
Real world, it did increase my HP in my old plymouth to the point where I could hit 3rd gear and stomp the gas and the clutch would start slipping where as, before the electronic ignition, it never had enough power to slip in 3rd. Its a definite improvement in starting, idling and mo' powa'!

Recalling dyno testing at Cubfest several years ago, electronic ignition versus points boosted torque output by 10%. Same Cub, same day, swapped out the ignition in distributor. It was nice to see the improved performance claim measured and proven!

I have some dist. parts in a box and it looks like I can go ahead and restore the 574 dist back to factory unit and get rid of all them wires.---Wish it only had 2 wires,--- but it don't! ---Looks like it was just something thrown at the tractor and that's the way they ran it until they threw a rod out the side of the block!
I have always had fair luck with points, so until something not so pricy comes along ,(never!) I will use points! thanks guys!! from sonny
