▶ Note:
For Both 12 volt and 6 volt setup.
In some cases you may want to use an external resistor to lower the ohms. But test your own setup before doing so
If Spark Plug Cap is defected or you needed a different degree Spark Plug Cap.
Just twist it off and reuse your old Spark Plug Cap or any others! Thank you!
The spark plug cap is removable, just twist it off and can be use on any other different degree spark plug caps.
Use a multimeter:
Primary resistance test, attach both positive multimeter lead and negative multimeter lead on the primary sides(input sides of the ignition coil).
Secondary resistance test, negative lead on the output side(wire without the spark plug cap)
and positive lead on the primary sides (both primary sides should get the same reading on the multimeter).
Now you can twist the spark plug cap(or your old cap) back on(tightly) to do the secondary resistance test again.
It should add another 5-10k ohms to the reading.
Please check the pictures and specifications for compatibility before placing orders.
