This tester will check the operation of all of MSD's single-channel CD Ignition Controls. Prove the ignition control and you can continue troubleshooting and find the problem.
The tester produces a simulated trigger signal that fires the ignition just as if the engine was running. A special, load-producing clip-on spark plug is included to connect to the coil wire. If the spark is unable to jump the gap of the tester, there is an ignition problem and you can track it down.
The tester also has a circuit to check the operation of installations using Digital Programmable 7 Ignition Controls which use a non-magnetic pick-up as sync signal for Individual Cylinder Management.
The tester has an LCD display that clearly shows the simulated rpm. This also allows you to test the accuracy of any rpm limits, rpm-activated switches, shift light operation and the tachometer. The Tester operates on 4, 6 or 8-cylinder engines and will simulate up to 16,000 rpm.
