Have checked all continuities and resistances, replaced CDI & coil, still no spark.

Anyone know what's supposed to be coming out of the pulse generator lead when starting?

Any ohter thoughts on what could be going on here?

 

Well, Honda has us checking them by peak voltage. Our reading is not in ohms anymore. To read peak voltage with your digital multi-meter, a peak voltage adapter is needed to obtain the correct reading. I purchased my adapter from American Kowa Tool. Shooting from the hip, an ohm reading should be around 250 (?)
On the other hand, if everything has checked out, like trying another CDI etc..., I have found voltage regulators to be the problem. 3 yellow wires are routed from the stator to the voltage regulator. One of the yellow wires enters the voltage regulator next to a green wire. The green wire is a ground.
Here is what may be going on. The ignition is powered from one of the yellow wires within the stator. Some times the voltage regulator shorts across inside between the yellow wire that powers the ignition and the green wire at the regulator, not alowing spark to occor. If you test the stator or if you test the voltage regulator, they will check out fine, although the issue lies within the voltage regulator.
I will try a test voltage regulator from my stash at work to diagnos this issue before selling the customer one. I have also seen pulsers fail. Also some trx300's depending on year will not trigger spark until the starter button is released. Making it harder to diagnos spark issues when checking spark at the plug

Thanks for the response.

Peak Voltage out on the Blue/Yellow wire from the pulse generator is .270 VAC when cranking.

R=.345 Kilo ohms, supposedly in rnage.

How do I check for a short in the voltage regulator?
