WARNING
ALL CONTINUITY TESTS MUST BE CARRIED OUT WITH THE CORRESPONDING CONNECTORS
DISCONNECTED.
HV coil primary resistance value:
Disconnect the connector of the HV coil and meas-
ure the resistance between the two terminals.
Characteristic
HV coil resistance primary value:
~ 0.9 Ω
HV coil secondary resistance value:
1) Disconnect the HV cable from the spark plug
and measure the resistance between the spark
plug cap and the HV coil negative terminal.
2)Disconnect the spark plug cap from the HV cable
and measure the resistance between the HV cable
end and the HV coil negative terminal (see figure).
3) Measure the resistance between the 2 ends of
the spark plug cap.
Characteristic
HV coil secondary resistance value with spark
plug cap
~ 8.4 kΩ
HV coil secondary resistance value:
~ 3.4 kΩ
Spark plug cap resistance value
~ 5 kΩ
