90 Ski-Doo Safari GLX no spark

I own a 90 safari glx (500 Rotax Liquid). I had to replace the coil recently however after a bout 2 hours of run time it is no longer getting spark. Not sure if its the coil, cdi, or stator. With the stator it appears there is a brown wire with 2 yellow wires coming off it. Both yellow to browns measure 69 ohms (hopefully these were the right ones to test). The sled only gets used for when we ice fish on and off the lakes. Is there anyway to test the CDI or COil fairly easily. Looking for any suggestions. Thanks.
