Hey guys, I picked up a polaris sportsman 90 that has no spark. Was told by the previous owner that it ran fine just a few weeks ago but died on his kid all the sudden. I got a new coil and installed it and it fired right up but only ran for 30 seconds then died again. Ive tried a new plug and even put the old coil back on but it still has no spark. What could cause the sudden loss of spark? Could the cdi be bad? Does anyone know the voltage or resistance measurements for the ignition system components? Im going to try and clean all the connectoins and check for continuity in the harness tomorrow. Any help would be greatelly appreciated. J
