12 volt coil, no internal resister. Wireing from switch to coil has external resister, another wire with diode in curcuit coming from starter solenoid or relay- this allows about 12 volts from starter to go to coil on starting, get strong spark. When engine running and starter not energized the switch circuit with resister will feed coil with about 7.5 to 9 volts of the about 14 volts in charging circuit. Diode in wire from starter cicuit will prevent backfeed to starter from coil. Short explanation of starter bypass use. Note that some small engine and early hot rod coils may run full 12 volts- warning on a Kohler replacement coil box. RN
