Ignition Coil Driver Wiring Diagram
So the coil driver wire seems to be fine.
Ignition coil driver wiring diagram. Ignition coil distributor wiring diagram size. This video concentrates on coils from an electronic point of view and reading wiring diagrams. I realise there are many videos of relay driven. The coils which are the basis for ignition coils and alternators have very specific electronic.
This is my ignition coil driver using a 12v 40a car relay and including a 500v 22uf capacitor. 800 x 600 px source. The transformer typically has only a dozen or so turns on the primary but many thousands on the secondary. I checked continuity in the coil driver wire from the 4 cylinder coil connector to the pcm and there is continuity with no resistance.
An ignition coil or spark coil is nothing more than a low frequency auto transformer with a relatively high turns ratio. Here is the schematic diagram of the circuit. With the engine running i am getting a reading of 13 4 13 5 volts on every coil connector by disconnecting one connector at a time and probing the power feed wire. Compared with a a switched pwm drivers this simple linear laser diode driver provides cleaner drive current.
