Ignition coil test
The coils may be checked using a hand-held multimeter. Check for continuity of the primary and secondary windings. The resistance readings found need not match standard values exactly. If the windings are in good working order, resistance readings should approximate the standard values.
Coil winding resistance:
- Primary: 0.11-0.21 ohm
- Secondary: 4.3-8.1 kOhm
Pick-up test
Disconnect the connector of the pick-up terminals.
Measure resistance across the terminals of the yellow/blue and yellow/green wires using a multimeter set to the 1000-ohm range. Correct reading is in the 190-300 ohm range.

Infinite resistance or a reading below the specified range indicates a faulty pick-up. Replace pick-up.
