[dragonsbear 0]

I desperatly need a wiring schematic for a Mdl 312-8.

engine specs:

47724d

mdl K3018

ser# 10041863

Any help would greatly appreciated

None of the 312-8's used a K301S-47724d nor did any other Wheel Horse model.

Kohler made serial # 10041863 in 1980

In 1980 they used a K301S-47723d in the c-125's.

In 1981-84 they used a K301S-47742 in the C-125's.

What is the model number on the tractor?

Do you have battery ignition and a voltage regulator?

Sounds like the engine has been replaced.

appologies for the slow response.. the id# 2112K805 32016

I don't know a lot about this tractor. Previous owners have wires running everywhere. There is a small silver thing with terminals on it i presume is a regulator. I need to get the tractor so it charges. It will run with a full charge on the battery but quits when the battery runs down. Put in a new battery and it runs till it runs down. I can wire a car but really need help with how to proceed with this.

Thanks much for the response. I hope the ID helps identify what it should have. The motor is really strong so if i need to change a bunch of things, I'm ready....

hi that number comes up 1988 312-8

As redhorse100 noted, the 21-12K805 model number indicates that your tractor is a 1988 model, which would have come from the factory with a Kohler Magnum M12S engine, not a K301S.

The wiring diagrams for that model are in Toro's demystification guide, which is available under the Files tab here on RedSquare:

That guide indicates that the wiring diagrams are identical for the 1987 and 1988 312-8 models, and I believe there's a wiring diagram for the 1987 model here:

Hope this helps!

==> Garry, did you happen to check Kohler's site to see where the 47724d spec WAS originally used?

[gwest_ca-(File Mod) 11,752]

Kohler has it labeled for Engineering Products.

Should have a 15amp stator and battery ignition.

dragonsbear - Does it still have battery ignition?

If the engine has the low oil switch the best wiring diagram is the 1986 416-8 model 31-16K802

If it does not have the low oil switch the best wiring diagram may be the 1985 417-8 model 31-17K801 if you can find one. This is a twin cylinder engine.

dragonsbear,

It looks like you haven't been officially welcomed here yet, so let me be the first to say

As you can tell, there's lots of good information here and plenty of good folks willing to share it. Look around, the more you look the more you'll find. And feel free to tell us about yourself and your Wheel Horses. :handgestures-thumbup:
