With the mag you can switch it out without doing anything but changing light bulbs. The generator may not charge it fully though. With the distributor you will need a ballast resistor or a different coil. I went to Farm and Fleet and bought one off the shelf for a car with a 12v system. The original coil will work for a short period of time till it gets too hot, maybe 5 minutes maybe 1/2 hour. When I changed the WD45 over I used an alternator off an old Chevy Blazer,new light bulbs and a new coil. She will now start at 0 degrees when I need (want) to push snow. Charlie

You might want to check the battery cables before you switch. You need heavy cables - none of those 12v ones. And the ground point needs to be really shiny clean. Polish the ground for the starter motor, too. Your 6v system can work just fine, but it needs to be fully up to snuff.

ac crazy - there are many factors that could be causing the results you reported. We don't have enough info to diagnose the cause(s). There are numerous sources of trouble that could be affecting the 6v system in either or both of your tractors. 6v systems are more demanding in that they will work fine IF the parts thereof are in good shape where a 12v system may be more forgiving. You could help us help you by telling us a few things:

Pumpkin Man....I think you're a bit off key....the crank starters were there so no matter what you could get one running....farm equip. didnt make money if it wouldnt start. 6v was the standard for ALOT of years and with some things still is....I had some problems with my 45 WC when I got it....I replaced cables, cleaned terminals, grounds, etc, took the switch of the side of the starter and cleaned both sides of the copper contacts because they were burnt, and kept messing with it....ended up my 1 year old battery that was in it when I bought it was bad....put a new 6v in and it fires up every time.....if you just take a bit of time to keep it up to snuff, 6v will never let you sit....its just not as forgiving as 12v....my WD has a GM one post on it and I hate it....Im gonna leave it 12v since it was converted and I had the starter built for 12v but put a 12v generator on it.......but its all in what you want I guess.

ok folks here it is..... tonight i cleaned all connections possible...the bolt for starter, cleaned nose cone of starter all brass and copper connections to starter, inside and out. the cables are 3/4 " in diam. good ends on both ends..... i reinstalled 6v battery which is new from yesterday, whirled over for first time and battery drained down.... so i stuck charger on for 20 min. worked good for a few min again. either starter needs rebuilt? or 6v battery isn't enough...now that is said....the starter works fine on the 41. the 41 engine is very tired and worn (ie) knocks a bit... the 44 has high compression so i believe that i will be putting the 6v in the 41 and a 12 in the 44 for now..i am getting tired of having to work on it for two days to get it to run for 4 hours a week.... if you know what i mean? i do appreciate the advise. it has helped me to figure out what needs to be done further... thanks again to all.....

As Greg says, these starter systems can be very frustrating. I know! But getting one to work sure brings a smile to your face. BTW, the higher compression on ac crazy's '44 C is probably NOT the source of the trouble. Yes, if everything else is the same, higher compression = slower starter rpm. My guess is that not everything else is the same, though. Often the problem isn't at all obvious. And I have to confess that, although I enjoy outsmarting the 6v systems, my D14 with which I plow snow was converted to 12v by a previous owner - and still remains so!

That'd do it, Charlie!

A C with 18.4-26's??? Could be a swamper!!
