No spark again

[Steve in Mo]

I have a Kohler K241AS 10 HP on a C101 Wheel Horse. Some weeks ago I lost spark, and after much trial and error replaced both the coil and the seperate condensor.She started and ran like a dream for about 2hrs. total Then just as before no spark. Have 12V to the positive on the coil and from the negitave the 12V come and go when you crank it over. This seems right to me. Is my coil bad again and if so what could have taken it out.
As always thanks for the help!!!!!

Did you use a genuine coil or AT LEAST a "true" 12-Volt automotive coil that does NOT need an external resistor?

For complete troubleshooting information, there's a link below to the factory service manual in .pdf format.

It could possibly be a bad ignition switch

If you only replaced the coil and condensor, you forgot the points. The also need to be replaced. Did you use s Kohler coil? If not, get the correct one from a Kohler dealer. Did you change the plug wire? If you did, did you use a solid cored wire? If you did not replace it, this might be the time to do that also.

You need to check for battery voltage at the coil with the ignition switch in the on position and the points open with a test lite or voltmeter.
Clean the points with some 320 wet or dry. If there's no battery voltage to the coil, check at the ignition switch for voltage being fed to the switch and voltage to the coil when in the run position. Could be a defective switch or there's a problem with the feed wire to your switch. You will need to trace that wire to where its connected. Could be on a solenoid. Hal
