Sorry, don’t have a four stroke manual…
The coil is a strange dual fire coil, meaning it fires both cylinders at the same time producing "waste spark" on the cylinder that is not on its compression stroke. So, to measure the secondary resistance you would measure between the two plug lead towers. I’m "guessing" the secondary resistance is similar to standard OMC coils of the day at several hundred ohms. Because this is a dual fire coil, there is only one primary circuit, and it is checked like a conventional OMC coil, between ground/strap and the primary tower, it will probably read less than one ohm.
Hopefully someone else has the manual and can post sensor and charge coil resistance readings, do you have a meter capable of reading peak voltage? If so, you could check the output of these components as well…
Hopefully the pack is OK, these are getting expensive and hard to find….Don’t know if the various independent suppliers can rebuild these parts…
Saw a few of these on ebay, very pricey, a few offered by CDI….Maybe they will discount slightly for a core return….
Hope it is something simple

I think these flywheels have an "encoder ring" underneath that is read by the pack, might be worth removing the flywheel to make sure this is not broken.
