How much resistance should a spark plug cap have?
How much resistance should a spark plug cap have?
Simply attach or hold a meter probe on each end of the cable and read the total resistance on the meter. The Society of Automotive Engineers suggests the maximum resistance should be 12,000 ohms-per-foot.
Why do spark plug caps have resistors?
Combined usage of the resistor covers and resistor spark plugs is more efficient to suppress ignition noise from engines in motorcycles, snowmobiles, farm tractors and so on. It has to ensure no current leakage occurs at this connection which will affect engine performance.

How do you test a small ignition coil with a multimeter?
If you have a multimeter, turn its dial to the 20 K ohm scale, and insert its red lead in the common jack and its black lead in the jack marked with the ohm symbol. Test the meter before checking continuity by touching the leads together and verifying that you get a reading close to 0.
Are all spark plug caps the same?
ALL spark plug wire boots (caps) are the same size. if you do go with a wire that has a rubber boot on it you will have to install the little screw on cap that goes on the tip of the spark plug.
