Measurement:
Remove the plug from the spark generator and the 8 way plug from the PCB, measure the resistance of the brown and blue wires on bottom row of the plug.
Also check the condition of the harness visually.
Expect continuity / zero resistance on each test.
Are the resistances measured as expected and is the harness in good condition?
