How many ohms should a plug wire have?
Question: How many Ohms of plug wire should be used? Answer: Usually between 10,000 and 12,000 ohms of resistance per foot of wire.
Can you Ohm a spark plug wire?
Use a digital or analogue multimeter (or ohmmeter) to check if the resistance of each spark plug wire is within the manufacturers’ guidelines. To do this, set the multimeter to the appropriate scale and measure the wire by placing the probes on each end of the wire lead, making sure they touch the metal contacts.
How do you plug a coil into a plug cap?
Using an old pair of cutters will simply mash the end of the Coil Wire. Install the NEW Rubber Boot over the wire, making sure the wide open end faces the Plug Cap End of the wire. Pull the boot back so about 1-1 1/2 of Coil Wire are exposed.
What kind of crimp do you need for spark plugs?
You will need a spark plug terminal crimping tool in order to obtain the correct crimp. These can be found at most any parts store or puchased from us. Also, you do not want to use cable coaxial crimpers or pliers as these can compress and crush the core of the wire.
What causes a plug cap to stop working?
Well they generally don’t suddenly stop working, they just build up resistance to the point where you spark gets weak and things don’t work like they used to. The symptoms of Plug Caps/Coil Wires/Coil failure are poor starting, some mid range lag and possibly Poor Gas Mileage.
What kind of spark plug to use with TCW wire?
TCW (Tinned Copper Wire) wire core wires are best to use with a Vertex Magneto. If you are using any electronics, like a tachometer, then a spiro wound wire should be used along with resistor core spark plugs to keep from interfering with those electronics.
How many ohms does a spark plug wire have?
The resistance of many wires is measured in ohms per foot. A wire with high resistance can be in the 5000 ohms per foot range for especially high-output ignition systems, whereas a low resistance performance wire could easily get double digit ohms per foot.
Using an old pair of cutters will simply mash the end of the Coil Wire. Install the NEW Rubber Boot over the wire, making sure the wide open end faces the Plug Cap End of the wire. Pull the boot back so about 1-1 1/2 of Coil Wire are exposed.
What should the resistance of a spark plug be?
If you get a higher reading than specified for your wires, replace all spark plug wires. Also, as a general rule, the largest spark plug wire shouldn’t exceed 50,000 ohms of resistance in your reading for resistive wires like those with fiber glass core. Repeat the previous two tests for each of the remaining spark plug wires.

Are low resistance spark plug wires better?
The higher voltage of a coil on plug or distributor system can create enough voltage that a slightly higher resistance wire will not greatly affect spark strength, but the relatively lower output of a magneto means using a lower resistance wire is more important to ensure a hot spark from the spark plug.
Why are high resistance cables used on ignition systems?
The purpose of this resistance, as already described, is to reduce electromagnetic radiation. This is achieved by limiting the current (I) through the ignition wire and simultaneously ensuring that the spark plug also receives the necessary voltage (U).
How can you tell if you have solid core spark plug wires?
There’s more to a plug wire than the color of its skin. The only way to accurately tell one type of wire from another is to go beneath its skin to reveal its core construction. Basically, there are three main types of ignition wire: solid-core, carbon-suppression, and spiral-wound.
Why do spark plug wires have so much resistance?
Spark plug wires have an outer insulation several times thicker than the conductor, made of a very flexible and heat-resistant material such as silicone or EPDM rubber. The thick insulation prevents arcing from the cable to an earthed engine component.
