1987 W.H. 310-8M10 Engine to Tractor Connector Wire Orientation?

[Railboy 12]

Hello, And onto a Topic for a 1987 Wheel Horse 310-8 Kohler M10 Engine Connector to Tractor Connector 

Wire Conformation with Correct Arrangement at Connection.

 

I have run into an issue do to Colors of Wires are not in diagrams, and the only Diagram I have seen with some

of the colors I am not sure on the connector where they go?

 

And yes, I need some access to more wiring diagrams to work this out.  In one diagram the Yellow Wire goes to 

the Head Lights, but to share, I can not upload this diagram do to access to download, wish I could to elaborate.

 

I have photos below of what I have currently from an Engine Rebuild, and Connector dismantling and reassembling that

I am not a 100% sure if correct.

 

Reason, I have a blown Stator that the images of the wiring currently could have contributed to.

 

So, I have seen one Kohler M10 Wiring Diagram with the Color Yellow, but no Black of the Stator.

 

Point it, I am going to track down the leads of the Stator to see where they go on the Tractor.

 

So, as you see, in the second row down from the hump, the hump is the White Magneto Wire Lead, which is correct.

But below on the Right side of the White Wire, is the Yellow, and then to the Bottom Left of the White, is the Black Wire.

 

Both Black Wire and Yellow Wire are Stator Wires with a Stator that has inline the built in Diode Rectifier.  Not sure which one really.

 

Thing is this.  The Engine was disassembled and rebuilt over winter, and connector taken apart.  And I have a Blown Stator, it does not pass

the Kohler's Stator Trouble Shooting Guide Test.  It failed a few of the test.  It Grounds out(One Wire to the Chassis), plus there is no continuity between the Yellow and Black

Wire's of the Stator.  No .1-.2 ohms.  These test came from the Site's Kohler's Trouble Shooting Section on Testing Stators.  

 

Also, my Stator is a Two Wire Stator with the Built in Diode Rectifier for conversion of AC to DC to charge the battery and I guess a few other things like Lights.

 

Thank you for your time, I am trying to collaborate that my wires are either wrong or correct before I install a new Stator and Wire it up to the Connector.  Making sure

I am avoiding a misconnection and hopefully the Stator works out this next time.

 

Thank you for your  help.

In a 3 amp unregulated system which I believe you are working on there are 3 wires in the engine harness.  The one with the lump (diode) is dc and charges the battery.  One is AC that powers the head lights when the engine is running.  The other is the magneto kill wire.

 

One confusing fact the colors in the engine harness are Kohler Looking at my 2 single Magnums the yellow wire  is the one the changes to green in the tractor side of the connector, and is the head light circuit.  One of the other two, will have a lump in it a couple inches in from the connector. That lump is the diode that changes the AC to DC for the charging system.  The other wire is the magneto kill,  Peel back the plastic tube to see the diode.

Thank you for all ya'll's input and also Ackto for the link to the wiring diagram.

 

I need to trace down the yellow wire and black wire to where they go to verify proper

placement in the connector.

 

Any ideas on the Black Wire off my connector, yellow on the diagram should have continuity off

the head light circuit with the lights on, I am figuring.

 

But this, and have to say, my new Stator is in the mail.  I will post a photo of it and connectors of it

for I have seen both male and female connectors on them.  But also, I will be seeing the color of the

wires for the first time once it shows.

 

But as pfrederi said, I may have to cut open the sheathing back to the diode(rectifier) to make sure of 

colors.  Which makes it and up in the air for me thing right now.

 

So, give me some time, but will be back with what I find out once the new Stator shows(Photos Posted).

 

Thank ya'll for your help, luckily I have not melted anything other than I guess the stator, not sure why(other than crossed up wires

or pinched leads at time of assembly or rubbed the flywheel), have to 

pull the shroud yet and flywheel yet to see, but need the tractor for cutting grass. The magneto does the Spark Plug so starts and runs

but frying the 15 amp. fuse at time of start-up, every-time.  Guess the Stator being grounding out on a lead is doing it.

Hello Folks, well the Stator showed up over the weekend.  Below is a photo and I am trying to identify 

the color of the wires at the connectors.  One for sure is Black, the other looks to be either faded Yellow

or White.

 

So have a question, how far up the wire leads do I need to go to get to the Diode(Rectifier) to verify which

wire is which.  As you can see in the photo, there is sheathing all the way to the winds.

 

Ok, and thank you, I am using the wiring diagram the best I can, but would like to know from the experienced 

what ya'll know on where the leads go, I know the Yellow/White Wire looks to be the headlights in a circuit, but the other, 

Black Wire looks to run into the White Wire on the Diagram to the Rectifier Input on the Ignition.

 

Also, at time of inspection of the Stator I just got, I have yet to do Test on it with my Meter, but I have to do some work

on the connectors, these on the Photo are Female and I have to swap them over to Male to work with the pre-existing Tractor,

so just going to cut out from the original Stator and solder them into the leads to slip back into the connector on the engine side.

Thank you for the help I am getting, been learning a lot on Wheel Horse Wiring Diagrams, It has been

a cash course for me being a Newbie at Wheel Horse.

 

Oh, last thing, is the Two Lead Connector Kohler Manual Trouble Shooting Guide the Proper Guide to follow Testing out

the Stator? 

 

[pfrederi 20,222]

The diode you are lookinig for is usually close to the end of the engine harness 2-4 inches from the connector heading to the tractor harness.

[Railboy 12]

pfrederi, so the Hump(Diode) goes to the White Rectifier Wire in the Ignition, and just put the other to the Lights?

 

See, I have my Ohm Meter and will track the wires via continuity to make sure the leads are in order to connect to the

tractor side.

 

Make since what I am getting at?  

 

Thank you for the correspondence and in reading the wiring diagrams, but yes, going by what I find in the sheathing(Diode) 

lay-out internally with the wires.

 

Oh, last question, the Kohler Trouble Shooting Guide is accurate for what I need to do before cracking into the chore

or install?

This is correct, but assumes the stator is mounted to the engine. If it is not yet mounted, then ground is the iron/steel frame of the stator. 

Also, because you are looking for very small amounts of resistance, make sure your ohmmeter is at the correct range and make extra sure to have solid, clean connections between the test leads and the stator connectors to avoid skewing the readings. 

 

Important: if the diode is in one of the stator's leads, then measuring resistance across the leads using an ohmmeter will show infinite resistance with the black and red test probes connected in one direction and the very low (0.1 - 0.2Ω) resistance with them swapped to the other direction. This is the diode blocking current in one direction but not the other. It takes only a minute to do the test in both directions for reassurance!

 

Follow the colors for connecting to the tractor to make sure that “plus” voltage is being delivered to the “plus” side of the battery for charging!

Yea I think I have a grip on this.  Just need to verify that I have the correct Stator and why I have the photo, plus where the Diode Wire goes, and I figure

the other is the head lights.  I am following the Diagram and coming up with two sources where the leads of the Stator go.

 

That is the Headlight Circuit, so that should be easy enough to find out, from the Tractor's Side of the Connector, and also, the Wire on the 

Tractor's Side of the Connector to the Rectifier at the Ignition.

 

Please correct me if I am wrong.  I do not mind...

 

I am looking at if I have the correct one, a new Ignition Switch.  I have an OEM 6 Connector Ignition Switch that is for a Magneto.  That is what the 

Vender said on the phone when I ordered it.  But yes, I paid the Wheel Horse Price.  And figure if the one that is on the tractor lasted 40 years, I should

be good for another 40 years.  Why I had the engine rebuilt.  So, thing is now is to do the job, why I am getting my ducks in a row.  I use the Tractor for

weekly grass cutting.  And with the Magneto powering the Spark Plug I am fine, just no battery charging.  But yea, blows the 15 amp. fuse at time of Start-Up

do to what I think is the grounding out of the Stator, for I found that in one of the Trouble Shooting Test.

 

Yea, getting it sorted and thank you for the info, but yes, just need to collaborate the Diode Side Wire in where it goes for Sure, plus the other Wire to Verify?

But as you can see from my photo of the Stator, my Colors do not match the Wiring Diagrams I have, so yes, I am removing the Sheathing off the Wires of the Stator

when I do the job to find out colors.

 

Thank you for ya'lls time.  Just being a Newbie, which I do not like but I am learning, lol...

 

Oh, Handy Don, I plan to go over the Trouble Shooting procedure again, and follow your lead.  But as of right now, I know I had a lead grounding of the Stator

out on the chassis..  Which Sucks...  Think that is why I am blowing the Fuse I think????
