Ignition Amplifiers/ Coils Monitors

Ignition Amplifiers/ Coils
The ignition amplifiers monitor is very similar in operation to the injectors monitor, albeit with different enable conditions. Please refer to the injectors monitor explanation and flowchart. The ignition amplifiers have two monitor lines that carry multiplexed ignition amplifier monitor signals whereas the injectors can be monitored individually. It is for this reason that the ignition amplifiers monitor does not operate over such a wide range of engine speeds as the injectors monitor.
