MSD IGNITION TESTERS, PN 8996
The Multi-Channel Ignition Testers, PN 8996, can check the channels of the MSD DIS Ignition Controls. It connects
easily and will simulate a trigger signal through the four (if used) trigger wires. A test plug is supplied that connects
to the spark plug wires and ground. When the Tester is turned on, a spark will jump the gap of the test plug
confirming operation of the Ignition and Coil.
Though designed for Multi-Channel Ignitions, the PN 8996 Tester can be used to test standard MSD Ignitions as well.

General Wiring
Trigger Wires
WARNING: Do not connect more than one channel of the Tester unless each spark plug wire is removed
from the spark plug in the cylinders and placed close to ground. If left connected to the plugs,
a spark will occur in the cylinder igniting any fuel in the cylinder.
Magnetic Pickup Connector
Violet and Green: These wires are routed together in one harness and form the magnetic pickup connector.
This connector plugs directly into an MSD Distributor or Crank Trigger. The Violet wire is
positive (+) and the Green wire is negative (-). This connector is used with standard, single
channel MSD Ignitions, not for the DIS Ignitions.
Cylinder Select: Push the Program Selection button on top of the Tester to select 4, 6 or 8-cylinder standard or DIS
operation.
