12 Volt WOW!!!

Postby ShawnAgne » Sat Oct 14, 2017 10:33 am

To say it starts faster with 12 volt is an understatement. I didn't think it would be that much of a difference, WOW was I wrong.....

Do yourself a favor and if you are running 6V convert it!!

No surprise. When you have about 2 times the amperage available to turn the starter motor that's what you get.

I love my 6 volt system. It's original, simple, reliable and works like a charm. :wink: I'm glad your system is working well for you.

Agree with Ricky. While using a 12v power supply to run a 6v starter motor will work it introduces other potentional problems especially if the starter is allowed to run more than just briefly. Excess heat, wear on the components, shock to the bendix drive, ring gear damage all are some of the gremlins in the box. There is a reason why IH redesigned the starter system when 12v was introduced. Just be prepared for the "fall out" if and when it occurs. :hattip:

I agree with the two posters above, hitting a 6 volt starter motor with 12 volts opens it's own can of potential worms. A well maintained 6 volt system, including a good battery and proper sized (gauge) cables along with solid connections and good grounds will serve these old tractors well. My Cub starts the instant I pull the rod, as it should. I ran my restored military jeep on 6 volts for 14 years, 10 on the first battery, without a hitch. By far the most common starting (cranking) problem on 6 volt systems I've seen in 60 years as a mechanic and restorer is mismatched cables. Most people think a battery cable is a battery cable but it isn't and using 12 volt cables on a 6 volt system is going to cause problems, especially starting (cranking) problems. Not saying that's the case here but it often is.

David, wasn't planning on doing that was just curious. As far as excessive cranking literally just tapping that starter and the motor is off and running.

Don't buy into the hype! Everybody thinks 12 volt conversions are so wonderful, when they can get the exact same results out of a 6 v. system with the proper gauge battery cables, (little auto parts store cables won't carry the juice, you need at least a 2/0 cable, GOOD auto parts stores can make them up for you) cleaning connections that haven't been touched in 60+ years, and having the starter cleaned and serviced. Of course, this requires taking a little time and care, so most folks hack up some new brackets, maybe maim up a little sheet metal, and send it. I have one 12 volt tractor, converted before I got it, and 3 that are 6 volt, and they start just as reliably as the 12 volt tractor.

12 volt conversions have their place, if you want your tractor to run a 12 v accessory, or if your original charging system is so fouled up that it will be crazy expensive to fix. I will concede Delco alternators are cheap. But most people use it as a band aid, or get all excited because 12 is 2x6, so it MUST be better! Also, don't buy the hooey that 6 volt batteries don't last. My last new 6 v battery replaced one that had been in the tractor for 5 years, with seasonal use and no trickle charger on it in the off-season. Wasn't any more expensive than a comparable sized 12 volt battery either.

On the old tractors I have seen converted, nobody has done anything to the starter, they run 12 v through it, so of course it will spin faster. Along as long as you don't just grind and grind and grind on it, it will take the 12 v. Of course, since the tractor now starts so magically wonderfully, that won't be an issue, right? :? :?

I have 6 & 12 volt cubs and think things other than voltages impact starting. My 49 was a pain for years until I really started looking into it. cables connections, clean wire connections, full tune up and proper timing, carb rebuild, electronic regulator, basically correction 60 years use and off spec fixes. Now it will start in 2nd gear after sitting for weeks.

I do agree with Super A that at some point it does make sense to go 12v. I have a sprayer and can only use it with some Cubs. If you have a dead generator the cost of a conversion in money and time may make more sense.

The biggest weak spot on the 6 volt systems is the regulator. If you go with an electronic one and maintain the Cub the 6 volt is just as reliable and quick starting as the 12 volt. The time and money spent switching from 6 to 12 just to make it "easier to start" may be better spent going over the systems and gettering them up to spec.
When you only have 9 horsepower you need to know the names of all of the ponies!

inairam makes a good point. I would say generators will last just about forever but regulators/cutouts seem to be the weak link. I've seen several good articles about diodes and stuff hidden inside the cases of old regulators. I may try that on my white demo Super A when I reach that point. One of my tractors does have a regulator with a "mind of its own" but it does enough to keep the battery charged!

Another which oil is best discussion.

After I sold my 1950 Ford pickup, the only 6 volt machine on the acreage was the standard Cub. The 6 volt system was still working when I converted it to 12 volts.

Rough count, I have 12 different tractors, vehicles, machines that use 12 volt batteries. If a battery dies, I have an immediate replacement.

For me, the 12 volt system simplifies things.
I have an excuse. CRS.
