This weekend its raining continuously in Islamabad, so thought of checking ignition system of my Khyber.
R-Spec 10mm Sparking Plug wires resistances: (Ohm-meter set to 20K setting)
Small wire: 0.70K Length: 22 inches
Medium wire: 0.76K Length: 23 inches
Large wire: 0.84K Length: 25 inches
Distributor to Ignition coil: 0.93K Length: 27 inches
These wires were bought and installed in March 2011. Working perfectly even after 5 years. High quality wires.
Ignition Coil Resistances:
Primary resistance (from positive and negative terminals of coil): 1.2 Ohm
Secondary resistance (from positive and HT terminal): 13.29 K-ohm
As primary resistance is low, smallest value was selected on ohm meter for accurate results.
The results verify that ignition coil is working absolutely fine.
Battery Voltage at Ignition coil: (Voltmeter set to DC Voltage)
DMM negative to battery negative and DMM positive to ignition coil positive.
Switch at ON position: Battery = 12.05V Coil = 11.3V
When engine is running: Battery = 14.38V Coil = 13.47V
There is a little bit voltage drop at the coil due to resistance of wires and connectors, but its negligible.
