Default 782 no spark coil question

Good day. I have a 782 (red) that has no spark on either plug. A test light on the negative side of the coil flashes on off when cranked over. The coil tests 4.2 ohms on the primary side but is infinite when measuring from primary to secondary side of coil. This is a twin coil. Does any one know what the resistance on the coil should be. I was assuming the coil is bad but ordered a replacement from off of Amazon and it tests the same.

Google was my friend. Coil testing starting page 32 assuming you have series II. Not sure if series I may be different.

Thank you . That resource from Kohler site is exactly what I was looking for. Looks like on the dual output coils for secondary you measure across the 2 outputs and not from primary to secondary like on old car coils looks like my coil is out of spec as it is half the resistance it should be when measuring it the proper way. Thanks again for pointing me to that resource.

Cub Cadet is a premium line of outdoor power equipment, established in 1961 as part of International Harvester. During the 1960s, IH initiated an entirely new line of lawn and garden equipment aimed at the owners rural homes with large yards and private gardens. There were a wide variety of Cub Cadet branded and after-market attachments available; including mowers, blades, snow blowers, front loaders, plows, carts, etc. Cub Cadet advertising at that time harped on their thorough testing by "boys - acknowledged by many as the world's worst destructive force!". Cub Cadets became known for their dependability and rugged construction.

MTD Products, Inc. of Cleveland, Ohio purchased the Cub Cadet brand from International Harvester in 1981. Cub Cadet was held as a wholly owned subsidiary for many years following this acquisition, which allowed them to operate independently. Recently, MTD has taken a more aggressive role and integrated Cub Cadet into its other lines of power equipment.
