My daughter was riding her 2008 suzuki quadsport LTZ 50 when it suddenly died. When it would not restart I began to check for potential problems. Conclusion= no spark. I checked for spark with my test light. I have spark at the flywheel wire and I have spark at the rectifier. I do not have spark or power from the 2 wires that connect to the coil. How do I check to my CDI box for proper function? I am either thinking bad CDI or bad coil? I am new to this site. Any help would be appreciated. Thanks Justin
