Don't risk the Kohler part doing experiments.
Use a cheap 12 Volt light bulb for load tests, for example a turn signal bulb (an 1156 is 25 Watts or less).
Test slow and easy. Make good connections. Label your wires.
Insure you have no short circuits, bare wires or things that will get tangled or mangled.
POST whatever results you get, before connecting that shiny new regulator, frying it, and then posting how its fried.
Connect one coil to the bulb. Idle the engine, measure AC Volts across bulb. Rev engine, note Voltage.
Stop engine. Disconnect coil from bulb.
Connect the other coil to the bulb. Run engine idle and fast, noting AC Voltages across bulb.
This indicates both coils produce AC Volts.
Now connect coils in series, and wire the bulb where regulator connects.
Run engine, measure AC Volts across bulb at idle RPM. You are looking for double Volts. If something seems wrong, like LESS Volts than just one coil, shut it off.
Swap the connections to one coil. Now idle the engine, measure AC Volts across bulb. Any improvement? If it looks like double the Volts from the single coil test, you may have something.
If neither series test produces Voltage, parallel connect the coils.
Idle the engine, check Volts. The bulb should be BRIGHTER than with one coil.
If you have an AC ammeter function on your multimeter, you should also check Amps on all these tests.
The goal is, once you blow out (maybe) a cheap bulb verifying what works, you then try the regulator and let it power the bulb with DC Volts. Idle the engine first, shut down quickly if you get no Volts.
