Onan 5000 won't start

Mark, mine just stopped running one day traced it down to no spark. After checking the sensors and other circuits I zeroed in on the ing coil. Each coil has ohm readings that will tell you if its good or not. The hardest part was to remove all the sht metal shrouding to get to the coil. Also there is a gap that has to be maintained between the coil pickup and magneto you can check that first before removing it.
