Hey folks, hoping I could get some advice on my spark hunt.
I've replaced the following components:
CDI
Ignition Switch
Kill switch
Stator Pickup Coil
Battery
Ignition Coil
Sparkplug
but still no spark.
I've also followed the manual's instructions testing resistance via the CDI, and every single pin fell within the ranges. I also bypassed the Ignition Switch and Kill switch via hotwire to make sure those components weren't faulty, and I still didn't get spark. I also cleaned up the Neutral and Reverse terminals on the bottom right of the engine as I heard those could be a culprit.
The only thing I think the problem could be is my pulse generator gap, or a bad ground at my pulse generator. I say that because I did a test mentioned here -http://www.3wheelerworld.com/archive/index.php/t-185320.html. This test said to measure voltage on the wires coming from the pulse generator when cranking the engine, and you should see < 1 volt. In my test, I didn't see ANY voltage.
So then I decided to test the resistance between the BL/Yellow and Green wires coming from the pulse generator, and I didn't read ANY resistance. But that confuses the hell outta me, because when I plug these wires back in to the plug leading to the CDI, I get the correct resistance (300 ohms) at the CDI!!
Does that mean I have a bad ground at my pulse generator? Or possibly a bad ground wire coming from the pulse generator? I just don't understand why I would have the correct resistance reading for the pulse generator at the CDI but not closer to the pulse generator....
Any help/advice is appreciated. Thanks :)
