Wiring question for the 99 Toad

[viclioce]

OK fellow Road Toad owner's. My owner's manual has a wiring diagram and it shows the set of wires coming off the magneto as having the blue & black which go to the coil (check), and it shows the plug which connects to the ignition switch as having a G BU Y & BK (check NOT).

My magneto plug set shows BU BK Y & YG with a side G wire not in the plug with a spade connector (see top photo). My ignition switch plug shows the traditional G BU Y BL with a separate G to go to the voltage regulator (see bottom photo). I have that extra loose G connected to the regulator now. If I plug things in based on the shape of the plug, the Y on the magneto plug lines up with the Y on the ignition plug & the YG on the magneto plug lines up with the G on the ignition plug. The BU & BK both line up fine on both ends of the plugs. Is this going to cause issues?

Why the difference? And where do I connect the extra G from the magneto with the spade connector? This is something I want to be sure of so there are no issues in the future. The Green Toad followed the manual exactly.

I don't have a point of reference because I got the bike in boxes. No take apart pics! Thanks! Victor

Had to research things a bit . . . and the results are not truly conclusive. But they are at a guesstimated 95 -99% confidence level. The green wire and the yellow/green stripe wires come off the lighting coil at EXACTLY the same point (on the Model 94 that is . . . which is the same as the Toad system, I THINK <-- that's a BIG "I think") - so "electrically" they are the same and could be "switched out" in the 4-way connector without problem. Which is what appears to have been done on the machine you have. So long as there haven't been "switch outs" of wires in the 4-way connector of the wiring harness . . . everything should be OK. Confirm that the yellow/green stripe wire from the mag on your machine is connecting to the green of the wiring harness 4-way connector - if so, that is OK. In your photo above, the magneto output green wire end should be insulated so it won't contact anything else.

It is interesting that the Road Toad wiring diagram in the Owner's Manual I have, and the one on the Strictly Hodaka web-site are exactly the same and NEITHER ONE shows the yellow/green stripe wire coming out of the magneto (which I'm sure is there . . . and IS there in your photo).

Yeah. I thought it looked strange! I'm guessing that maybe they ran short of green wire during a production run?

Both of my Toads have VIN plates dated April 1975. So they must have come off two different production runs, is my educated guess. There's not a clue about there being a possible color substitute in the owner's manual tho.

Anyway, I guess I can just tape over the end of that "extra" green wire on the group of wires which terminate in the ignition switch plug? I almost thought the Green loose wire should be moved to the plug and the Yellow Green was pushed in by mistake.

I'll remove the magneto cover and trace the YG & the Green, and see where they terminate. Thanks! ; D Victor

I wanted to add to what Ed was saying. I think you actually have a Wombat ignition. Theoretically it will work but you have to make sure the wire connections are correct for a RT, as Ed was saying.

In the Wombat ignition, the green and yellow-green from the mag are interchangeable. You can use one or the other. Typically, the unused wire is tucked back down inside the sleeving to protect the exposed connector.

In the RT ignition, the yellow and green wires are switched and the yellow-green does not exist.

You'll need to verify your connections to make sure it will work.

In the Wombat ignition, the light coils are wired in series. This means that the maximum output is the sum of the two. Each coil outputs about 22W, so the two together output about 45W. The green and yellow-green are attached to the first light coil for 6v max 22W and is used to charge the battery, stop light, horn, and speedo lights. The yellow wire is attached to both for 6v (regulated) and about 45 W to power the headlight and taillight in addition to the battery, stop, horn, and speedo lights.

In the RT ignition, the coils are also wired in series. The yellow wire is attached to one or both coils, I'm not sure, to power the battery, stop, etc. And the green, is attached to both for the headlight circuit. Also the green wire from the mag does not pass through the key switch but ties directly to a double connector that goes to the regulator and the headlight circuit.

I believe the Wombat ignition will work, but since you had a box of parts, it would be prudent to verify What your parts are. Just keep in mind that the yellow and green wire sources were switched on a RT vs Wombat.

When you say Wombat ignition, do you mean the switch, or are you referring to the stator? It's my stator which has the YG wire.

Hmmm... Now that I think about it I should ask Danny! He sent me this stator! Victor

[rlkarren]

The stator plate may be setup for a Wombat. I believe they are the same, just wired differently. Which is what you'll need to check.

I've messaged Danny Cooke to ask him. He sent it to me so he would likely know from where it came! Victor

[viclioce]

Talked with Danny today. Yes the stator was from a Model 94. He said either wire will work but suggested I switch the YG with the G and tuck the YG into the harness cover. So now it will be Green to Green and we confirmed with the Model 94 diagram & the Model 99 diagrams as well for what the Green wire activates! Victor
