I lost spark on all cylinders and began troubleshooting using cdi manual. everything was within specs using my fluke digital meter except trigger voltage. I replaced trigger and now have spark for about half a second. Engine will start for a split second then loses spark and will crank but will not try to start until I wait 2 to 5 min and then it runs for half a second or so and loses spark again. Stator is putting 250 volts on high side 38 on low even when engine is not firing. Bad switvhbox or is it possible Im getting bad reading from stator? I do not have dva adapter
