Multi-Channel MSD Ignition Tester
PN 8996
These instructions detail how to use the Multi-Channel tester with an MSD 6, 7, 8, 10, Digital 7 Series Ignition
Control or Multi-function Controllers. If you need to test an MSD DIS Ignition, see pages 5 and 6.
WARNING: Do not connect directly to the coil or this unit will be damaged.
PARTS INCLUDED:
1 - Digital Ignition Tester
PROGRAMMING
The MSD Multi-Channel Ignition Tester
has the ability to test several different
combinations of ignition setups. By
pushing the Red button on the face
of the unit different programs can be
selected. Figure 1 shows the different
applications.
When you first connect power to the
Tester, the LED will display the name
and Part Number. You can bypass this
information by pushing the Red button.
The Tester automatically defaults to the program for an 8-cylinder, single trigger ignition system. To select
a different program just press the Red Select button until the program you need is displayed.
Note: If you have an MSD DIS Ignition Control, two test harnesses are offered to make testing each
channel of the ignition easier. The DIS-4 Test Harness is PN 89964, the DIS-2 is PN 89962. These
Harnesses will allow you to test the ignition and coils without having to splice into any wires. Figure
9 shows the harness.
WIRING
The Digital Tester has several wires with boots and alligator clips on each one. The wires with White
boots are all trigger wires. Note: All of the wires are only used when testing a DIS-4 Ignition Control.
Red: Connect to 12 volts.
Black: Connect to a good ground source.
White: This is the trigger wire used to test the points/amplifier (white wire trigger) circuit of an
MSD Ignition. When testing DIS Ignitions, this is the Channel 1 trigger.
Green: Channel 2 for a DIS Ignition.
Yellow: Channel 3 for a DIS Ignition.
Violet: Channel 4 for a DIS Ignition.
Green/Violet: This 2-Pin connector is for testing the magnetic input circuit for MSD Ignitions. It plugs
directly into the MSD’s magnetic pickup connector. Violet is mag + and Green is mag -.
Lt. Blue/ This is a 2-pin connector for testing the cam sync pickup circuit of an MSD Programmable
Ignition or Multi-Function Controller. It plugs directly into the MSD Digital 7 Programmable
Ignition's cam pickup connector. Lt. Blue is cam (+) and Lt. Green is cam (-). The CPC
Ignition is supplied with a harness adapter.
