This tester can be used with all of MSD's CD ignition controls as well as our line of DIS multi-channel ignitions. There are four points-style output wires that can be used to trigger the four channels of the DIS-4 ignitions, or a single channel can be used for ignitions such as the MSD 7 series. There is also a magnetic pick-up connector for racers using an MSD distributor or flying magnet crank trigger. The tester is easy to connect with firm grip alligator style terminals and matching ends for trigger inputs. The LCD alphanumeric readout displays the simulated RPM so you can easily confirm rev limits or the operation of an rpm-activated switch. For use on 4, 6 or 8-cylinder engines with a distributor or with coil packs.
