Testing Shielded Extensions
Many applications require the use of shielded or unshielded extensions.
This can occur when the spark plug resides deep in the “well” of a valve
cover. Shielded extensions can be tested in the same fashion as shielded
secondary leads.
Unshielded Secondaries:
Evaluating unshielded secondaries can usually be performed on the
engine as it is running by visual inspection. Replacement would be
required if voltage is seen “arcing” out of the secondary lead.
Unshielded Extensions:
Please contact I.T.S. for information on how to properly test unshielded
extensions (like those used with flange mounted coils).

Wiring Harness
CHECK FOR AC AND DC VOLTAGES ON THE
DEVICE TO BE TESTED BEFORE CONTINUING.
A point to point check of the ignition harness should be performed using
an ohmmeter to confirm continuity and ensure that a low resistance path
exists between the ignition system and the ignition coils.
6.1 Continuity Testing
Resistance tests below will be performed with an ohmmeter set to the
appropriate range (refer to your manufacturer’s operating manual).
6.11 Ensure all ignition coils, shutdown lead and leads to ignition
source have been disconnected.
6.12 Determine the engine firing order and wiring pattern.
6.13 Place one lead of the ohmmeter to pin “A” from main the
connector of ignition harness and the other lead to its termi-
nation point (ie. “A” or “+” of cylinder #1 ignition coil).
