To check the resistance of Top Gun ignition wires, you will require the use of a multimetre.
Set the multimeter to the 20K ohm (= 20,000ohm) range and measure the resistance of the cable.
When measuring the resistance of your ignition wires, please allow for: 1) variation in lengths ie. longer ignition wires will have a higher resistance than shorter ignition wires.
2) + or - 20% variation in results, being manufacturing parameters
Top Gun manufacture a variety of ignition wire types, to suit various applications. The resistance and construction of the conductive core used can vary depending on the different cables.
The four main ranges are:
1) 5mm, 7mm & 8mm
Spiral Wire
Standard kits designed
for General Passenger &
Commercial Vehicle use
Resistance range:
Approximately 5,000 -
6,000 ohms per lineal metre

Resistance range:
Approximately 2,000 -
3,000 ohms per lineal metre
4) 8mm Top Gun standard suppressed ignition wires, as found on loose lead merchandising racks (usually blue or grey in colour). Resistance range approx. 8,000 - 10,000 ohms per lineal metre. Please allow + or - 20% variation in results, being manufacturing parameters.
NB inaccurate results can come from a flat multimeter battery, and also from dirty multimeter probes.
