Secondary Quick Check
During diagnosis of a secondary ignition system you might encounter situations where you want
to display information on one specific cylinder. A Diagnostic Trouble Code (DTC) such as a P0302
(cylinder #2 misfire) would direct you immediately to the cylinder. Secondary Quick Check gives
you a quick and easy way to look at individual plug wires in the secondary ignition system by
simply hooking up one lead. The Secondary Quick Check utilizes a pre-configured display based
on the Secondary Ignition function.
The Secondary Ignition Lead is connected to the Sec Ign port on the tester and then clamped to
the plug wire. Connecting this lead directly to a plug wire will give you a cylinder ignition output
display on Distributor (DI), Distributorless (EI) and Coil-Near-Plug (CNP) systems. Be sure to
connect the secondary probe shield to a good engine ground.
