Our Ignition Module, Distributor and Coil Tester is indispensable for fault finding I Distributer and Distributerless (DIS) electronic ignition systems.
It tests both Hall Effect and Magnetic type modules and also checks the coil current across the RPM range. The coil tester can verify the performance of conventional as well as multiple coil packs.
The distributor tester checks that the magnetic or hall pick up in the distributor sends the correct timing pulses to the module or ECU. The distributor tester can also test the crank and cam sensors.
Frequently Asked Questions:
What is a DIS Tester? DIS ( Distributerless ignition Systems) operate without a rotating distributer to distribute the HV spark to the Spark plugs’. This is achieved in a number of ways: 1. via a pencil coil per plug and an igniter per plug driven from the ECU. 2. via a single module with multiple coil drivers driving a multiple coil pack for wasted spark i.e. one coil drives 2 cylinders. Drive signals from Cam and crank sensors to ECU 3. via a single module with multiple coil drivers driving a multiple coil, dedicated coil per cylinder .Drive signals from Cam and crank sensors to ECU
Is this a DIS TESTER? Yes. The tester simulates all pickup signal, whether Hall or magnetic, either from the Cam or Crank sensors or the Distributer. These signals then drive the ignition module which fires the coil.
Is the ECU function tested? NO. The ECU controls the firing sequence and spark timing based on internal ignition maps. A pulse from the ECU would fire the coil; this is what the module tester simulates and tests.
Can I test the module while still mounted to the coil and distributer? In general, NO. All components must be separated and tested individually. Some coils have in built modules. These can be tested together as described in the hookup diagrams
What is the difference between a module, and igniter or an amplifier? They represent the same function: historically Modules for distributer type systems and igniter/ amplifiers for DIS systems.
Will a faulty module destroy the tester? The tester has many built in protection features. However, careless handling of the HT lead during coil testing or not earthing the spark tester/ spark plug could damage the tester.
