It will also let you check rev limits, rpm switches and the camshaft sync signal of controls with Individual Cylinder Management circuits. The Tester connects easily to a 12 volt source, ground and a trigger wire. The PN 8998 will simulate a trigger signal through either the points (White) wire or magnetic pickup connector of the ignition. A test plug is supplied that connects to the coil secondary wire leading to the distributor 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. The PN 8998 is designed for testing single channel MSD Ignitions such as the 6A, Digital-7 and even the MSD 10. It can also be used with MSD Timing Controls. For Multi-Channel Ignitions, see page 128. Note: The Tester, PN 8998, supercedes PN 8995. General Wiring Red: Black: Connects to switched 12 volt source. Connects to ground. Trigger Wires White: Connects to points or an ignition amplifier output. When this wire is used the Magnetic Pickup is not (Violet and Green). 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 (-). When this connector is used, the White wire is not. Cam Sync Light Blue and This connector is used to confirm the cam sync signal for use with Individual Cylinder Green: Management circuit. When the engine runs, it will show “Cam Sync - Sync” for a good signal “Cam Sync - None” if there is a problem. Cylinder Select: Push the Program Selection button on top of the PN 8998 to select 4, 6 or 8-cylinder operation. (There is a toggle switch on the PN 8995 for cylinder selection.) 125 www.msdignition.com email: msdtech@msdignition.com AUTOTRONIC CONTROLS CORPORATION • 1490 HENRY BRENNAN, EL PASO, TEXAS 79936 • (915) 857-5200 • FAX (915) 857-3344 MSD IGNITION TESTER TO MSD 6 SERIES IGNITION WITH POINTS MSD IGNITION TESTER TO MSD 7 SERIES IGNITION WITH MAG PICKUP 126 www.msdignition.com email: msdtech@msdignition.com AUTOTRONIC CONTROLS CORPORATION • 1490 HENRY BRENNAN, EL PASO, TEXAS 79936 • (915) 857-5200 • FAX (915) 857-3344 MSD IGNITION TESTER TO MSD 7 SERIES IGNITION WITH TIMING CONTROL Note: The Obsoleted PN 8995 Tester will not work through the magnetic pickup of a timing control.
