Igniter: Description and Operation
PURPOSE
The igniter physically fires the ignition coil in response to the Electronic Control Unit (ECU)'s signal. Computers generally produce low amperage
signals as outputs, the igniter is essentially an electronic relay. It receives a "trigger" from the ECU and responds by turning a higher amperage
current to the ignition coil on and off.
OPERATION
Computers generally produce low amperage signals as outputs, the igniter is essentially an electronic relay. It receives a "trigger" from the ECU
and responds by turning a higher amperage current to the ignition coil on and off.
CONSTRUCTION
The igniter consists of a power transistor and circuitry to provide a tachometer output.
