• Check all system connections before performing this
inspection. Loose connectors can cause incorrect
readings.
• Check the cylinder compression and check that the
spark plugs are installed correctly in the cylinder
head.
Disconnect the spark plug caps from the spark plugs
(page 3-6).
Connect a known good spark plug [1] to the spark plug
cap and ground it to the cylinder head as done in a
spark test.
With the connectors connected, connect the peak
voltage adaptor or Imrie tester probes to the ignition coil
primary terminal [1] and ground.

The battery voltage should be measured.
If the initial voltage cannot be measured, follow the

• Although measured values are different for each
ignition coil, they are normal as long as voltage is
higher than the specified value.
If the peak voltage is lower than the standard value,
follow the checks described in the troubleshooting table
