I have an otherwise good 900 zxi but it lost spark while running. I believe it is the CDI box. I took everything apart and cleaned all the connections in the enclosure...still no spark.
Here are my questions:
1) Is there a mag test? voltage while turning over perhaps? just to be sure it is the CDI
2) Is there a CDI test?
3) what CDI boxes are interchangeable? this one is rev 3737. I know what the wires are for so I could hard wire one with different plugs if it would work.

All help is appreciated thanks
