680-16hp briggs elect?
 

Can someone shed some light on the wiring for this combo? On the side of the block next to the starter is the voltage reg (I think) with a single red wire and a small stud that looks like a ground. My wire harness has a large red wire (starter) and a plug that has a gray wire and what looks like two pink wires in a single spade, the question is what to do with these wires? I think the two pinks would go to the red wire and the gray to the stud but I don't know and i don't wont to fry anything, so if this is good or there is more to this please let me know.
Thanks Dan

You need to get a wire diagram and study it.

You are going from a coil ignition to a mag ignition....yes....no...?

On a coil harness you will have a power wire to the coil. On a mag harness you will have a ground wire to the mag with will shut the motor down. Two different harenesses and ignition switches.

Some will say that it's a simple one wire fix....adaption....well I wish it had been that simple for me.....

I rewired a mag harness to make a coil harness and all is well but the pto will only run with the lights on...I'm going to start over again when I have time.

For example...the kill/safety switch at the seat is designed to "GROUND" a mag motor.....well you are not grounding a coil motor, what you are doing is opening the hot circuit and killing power....

The switch is different and the wires in the plug are in different positions.

I made two mistakes with mine....one is I made up the harness on the bench and wrapped it up and then I was short on the starter wire....wouldn't reach the soleniod....unwrap and start again...... and the second was the deal with power to the pto switch that I now have to fix...

New switch, rewire and think it through..

The answer is...of the motor the wires from the regulator run to the hot side of the ignition switch to charge in the run position... the other wire is the ignition ground switch...

You'll need an ignition switch for say a 1811.

Or a relay and a few extra wires...I'll see if I can find a wiring diagram that'll help.

Scott, Matt, thanks for the help! I figured it wouldn't be that easy thats why I asked. A wiring diagram would be great! Theres a company on line that repowers stuff but unless you are buying a kit they're not very helpful, but they're trying to run a biz so I guess I understand. This swap is getting interesting, stuff I didn't think about when I started... but thats half the fun of it! One step at a time.

Thanks Dan

Dan:

Check your E-Mail. I have sent a Wiring Diagram.

R Bedell Thanks for the wiring diagram, this must be how the 680 is wired for the Kohler, so now I just have to figure out how to rewire for the briggs. I'm not sure what changes need to be done, as Murphycc stated there are some wiring changes that need to be done and this is where i'm lost. So if anyone has experience with this PLEASE help!.....the grass is getting tall:biggrin2.gif:

YES, that is because the tractor rolled out of the Factory with a Kohler.

NOW...retrofitting a B & S in this tractor will require some modifications.

With regards to the electrical side of this problem, one would need the B & S model number to specifically know how to wire this up.

Roland-

Do you have the diagram handy for putting an M18 into a 782? That requires similar wiring. He's putting a magneto ignition engine into a tractor wired for points/coil ignition, which is just like putting a Mag into a 782.

I've got a harness and switch I can send you, it's from a 1210. That should make it simple. Let me know.

Scott

This is a Diagram for installing a Kohler M-18 into a CCC built 782...

This is the Relay needed for the modification...

Thanks Guys! are the ignition and PTO Sw the same? What is the rev relay and the rev 6w, do I need these?

The ignition switch on a 782 and the 680 are probably the same. I imagine the PTO switch would be, too. You won't have (or need) the reverse relay or reverse switch, as those came later on.

I'm interested in that wire harness for the 1210 how can I get in touch with you?

The 1210 is a mag harness, Starter location and so forth may be a little off but the harness is complete and will suit your set up, may need to reroute a wire or two but....

Just pay shipping and it's yours...with ign switch.

Scott

Murphycc, thanks for the harness! It looks pretty straight forward but I have a couple ? The wiring diagram I got from R Bedell shows letters at the terminals but none of my parts have these letters on them so i'm sure how to check it. I'm not sure about the wiring by the fuses, I have two red or orange wires and a doubled up white and a single white and then two yellow that I think are the hr clock. By the motor there is a three prong plug,I only have one wire off the ign module so i'm not sure about this. Would anyone have a diagram that shows the harness as it really is and what parts they go to?
I hope I'm making sense, please bear with me.

You need to look at a mag diagram, preferably one of a 1210, and look at the ignition switch, now look at the plug as though it were connected to the switch. You should be able to trace out the wires that way. The two switches I sent you should be good and I think both are mag switches. The only thing I can think of that you may need to trace back are the alt/charge wire and the mag kill wire of which the plug may be different than that of your Vanguard.

BTW Dan, if it were me I would do two things-

I would first take the bundle out of the loom and after I got the harness figured out I would take it back off the tractor and wrap it up real nice with tape, much cleaner look and better protected in my opinion.

Secondly, I would connect all the wires that are obvious, that should be about 80% of them, once that is accomplished it's much easier for me to concentrate on the 20% that need to be figured out.
