I know it's been on here many times but I cant remember. What size wire do you all like for 6 volt?

Oops. Battery cables. SV got it.. thank you.

Size 0 or 00.
An auto supply that deals in truck and heavy equipment can make them up for you.

It depends on the tractor and length of cable, but for an old 6 volt typical mid sized tractor I recommend 1 Gauge absolute
minimum, but prefer 0 better yet 00 battery cables. Bigger cable = less line voltage drop leaving more for the starter where
its needed most. For no more then the cost difference especially to help starting in cold weather some 00 copper welding
cables are a great choice

I dont know of any near me that make them. I could probably make them myself but may just buy some on Ebay.

I will probably go with 21 inch. My auto electric guy sold me #2 in the past which I thought was small but took his word for it. Might be ok as they went very long. I want to make sure this time. Kind of a test. Put a new solenoid on it today and it stuck probably caused by old cables. I have a,12v in it now but going to see if I can make it work on 6v mainly as a experiment.

Don't know if you have an O'Reilly's in your area but I can buy 0 and 00 cable from them and the ends etc. from them

I've had them made at an implement dealership.

O'Reilly along with most parts houses here are a joke. I could get the parts but probably cheaper to buy them on ebay.

John T 2 may have worked but on freshly rebuilt engine with oversized pistons it didnt work. Of course the new starter switches are junk so that may have been a,problem aswell as a old starter. I dont want to go that route again. Lol.

Yes! Original size on the letter series Farmalls was 2 gauge. 1 gauge is a BIG improvement. Absolutely NO reason to ever go bigger than 0 gauge.
I used 00 on my MH55. Cable fits perfectly in the factory
clamps. To listen to it crank, you would never expect it to start.
Usually the second piston over compression fires.
My experience has been DelCity or Waytek are the best
places to buy battery cable, ends, and heat shrink tube.

The bottom line simple physical electrical facts are BIGGER CABLE = LESS LINE VOLTAGE DROP AND LESS WASTED I SQUARED R HEAT
ENERGY LOSSES regardless of the degree
Sooooooooo sure 2 Gauge works HOWEVER 0 or 00 works better in delivering more energy to crank the starter versus wasting
and loosing it in the cable/resistance.....
I support anyones free choice to use what cable they like (sure 2 works) but for no more then the cost difference and
especially cold weather starting in bigger higher compression tractors THERES GOOD REASON TO USE BIGGER CABLES
Now use what you like but electrical and physical facts remain the same

Olliejunkie, 21" battery cables are very long in my book. I am used to the cables on my 8Ns which are approximately 10". An engine in good tune will start reliably cranking at a very low speed. I tried an experiment one cold winter day when one of my Ns did not want to start. I connected the ignition system to a small fully charged 6 volt battery - this battery did not provide any voltage to the starter. The tractor cranked very slow, same as before, but now fired right up. Small battery cables can cause slow cranking speed - that is the part you hear. The same voltage drop that causes the slow cranking speed is also stealing voltage from your ignition. I would maintain for 6 volt systems the no start is more times due to no spark rather than low cranking speed. This is the principle behind gear drive starters; the low cranking speed reduces the load on the battery, thereby, saving voltage for the ignition.

I always use 2/0. Ya, it's overkill but, I
never have a problem cranking the engine
over.
