Should it be reading this voltage without cranking the engine over?

I have been working on a 2004 arctic cat 400 that will run for a while with a new coil installed then after a few min start sputtering and quit. Checking the coil afterward it it is burned up. There is 350 Plus volts going to the coil and I'm not sure if I need a CDI or its something else? Flywheel magnets have been ruled out!
