Dyna-S problem

I´ve bought last August Dyna-s, Dyna wires and green coils. After the installation my bike (KZ650) rans really great but now i´ve loosen 2 cylinders (1 and 4). I´ve checked all and the problem seems to be a failure on a Dyna-S (1-4) module:
-Module 1-4: magnet facing the sensor: 0.94 Volts, and magnet pointing away from modules: 10.61 Volts
-Module 2-3: magnet facing the sensor: 0 Volts, and magnet pointing away from modules: 10.50 Volts (checking at the coils)
Am I right?
Any suggestions or info would be appreciated.

I believe those to be acceptable levels. Here are two things you can do to diagnose if it is a pickup or coil problem.

- Take all plugs out and lay them on the case so you can check for spark while doing this.

To check pickups and coils.
- Switch the outputs of the Dyna and see if the the problem follows the output. If the problem switches to the other coil, then you have a bad pickup. If it does not then you more then likely have a bad coil.

Im guessing bad coil. Be sure to check voltage inputs on coil.

If not already done, would also assure sufficient space (or insulation) between ignition coil primary terminals and mounting spacers.

With Dyna coils, the heads of the screws that attach the wires to the primary terminals of the ignition coil are sometimes too close to a mounting spacer, which causes a short to ground and thereby prevents the ignition coil from functioning.

Good Fortune!

There are spark on 2 and 3 but not in 1 and 4 cylinders. Primary and secondary resistance checks are ok on both coils. There are sufficient space between ignition coil primary terminals and mounting spacers. And yes, i checked the voltage inputs on coils, but i think those 0.94 Volts should be 0.

Coil could still be bad. Switch the wiring to the coils and see if the problem stays with the coil or moves.

Bountyhunter, i´ve Switched the wiring and both coils seem to be ok

sounds like it's the pickup or ig module.

Where either coil will fire its two plugs when attached to the signal wire from the right-hand pickup module; and neither coil will fire its two plugs when attached to the signal wire from left-hand pickup module --- indicates a possibly bad left-hand pickup module or an issue with the signal wire such as shorted or internally broken.

As known, the coil charges while the signal wire remains grounded through the pickup module, and fires as the signal wire becomes ungrounded when the rotor magnet passes the pick-up module.

Good Fortune!

You may want to check the wiring that comes out of the ignition cover, to behind the engine. I just had an issue with mine sitting on top of the muffler, and melting the insulation. You may have a similar problem that ended up damaging the wires.

Thanks for all the replies. I rechecked everything and tried to contact with Dynatek because Dyna S is under warranty but do not answer my emails, so i will call them (a nightmare due to my poor spoken english)

Spark seen on 2/3 is signaled to coil from 3 o'clock module.
If same signal wire from 3 o'clock module is attached to the other coil, should spark on 1/4.
Sparking plugs from either coil using signal wire from 3 o'clock module indicates the module is okay.

Repeat the test on the other coil using signal wire from 9 o'clock module that does not spark 1/4.
If module is bad, will not spark 2/3.

Good Fortune!

Good thought. I would also replace the spark plugs for 1/4, as they have probably been fouled by gas and won't spark when wet.
