Dyna S install

Just noticed that on the Dyna S I just installed on my project bike that the two leads from the pickups are a black wire with a GREEN band where it is supposed to attach to the coil and a WHITE wire with a BLACK band where it is supposed to attach to the coil. I had considered the reasoning for putting the colored bands to indidcate one wire is supposed to be the 1/4 coil wire and one the 2/3 coil wire. Kaw almost always uses BLACK as the 1/4 wire and GREEN as the 2/3. Unfortunately, the bands were on the wrong wires. The white wire is coming off the right pickup which is the 2/3 pickup and it carries the black band. Go figure. Keep this in mind if you install these things and use the band colors as an indication of which coil to connect to.

maybe your advancer rotor is 180-out? Just a possibility.

Nope, George is correct, the DynaS wires are color coded backwards, threw me off for a while too when I installed a DynaS on my 650.

Maybe they have a test mule KZ and their rotor is backward. :blink:

On a points Kaw, the right set of points as you view with the points cover off, is the 2/3 points. The wire is green. The left set of points is the 1/4 points and the wire is black. On any Kaw I have seen with pickup coils and IC Igniter, the right pickup is 2/3 and green wire and the left is 1/4 and black wire. I am not sure what you mean by a rotor... The thing that sits in the middle of the mechanical advance? That only goes in there one way. The advance can only fit on in one way as it is keyed. They just assemble the wires wrong... I install quite a few Dyna S units and they are all like this now that I think about it. Why? Probably no one has brought it to their attention. I shot Jeff S. a note on this subject and hopefully he will mention it to them. I guess I should send them an email directly.

The stock rotor on a KZ electronic ignition can go on two ways. One way is right, the other is 180 out. Being 180 out makes the 1-4 coil the 2-3 coil and vice versa.

The Dyna III rotor can go on either way, and if I recall, the Dyna S uses the same rotor.

While the advance unit can only go in one way, the rotor can indeed go in 180 degrees out (as can the points cam) - there are two recesses on the back end of the rotor, one for each advance weight.

Here´s what the installation sheet for the DynaS (DS2-2 for the 650) says:

"While holding it (the advance assy) with the 1-4 side pointing up, slip the DynaS rotor over the shaft. A magnet approximately 1/4 inch in diamter will be noticed on the side of the rotor. This magnet must face to the left when the 1-4 side on the advancer assembly is pointing up. Spread the weights and push the rotor down until it engages the weights."

But the color codes are still backwards. Didn´t realize it was a common problem until now, just figured they messed up the one I got, they should be told.

Uh oh......

when I put the dyna on the 650 it was backwards also,

I have a Dyna-S 2 sitting in the box waiting to be put on my SR. I noticed the white wires and the black and green shrink tubing at the bullet ends, but didn't figure they'd be wrong. Thanks for the heads up!

Now I have to go out to the garage and look at it again. :pinch:

I will tell you if mine is backwards when I get home tomorrow..after I get done mowing...

I got my new one (Dyna-S 2) out of the garage and it appears to be correct. The white wire with the black band is connected to the left pickup and the black wire with the green band is connected to the right hand pickup.

I'm glad that I was able to double check this.
