Ignition Coil Driver Wiring Diagram
The transformer typically has only a dozen or so turns on the primary but many thousands on the secondary.
Ignition coil driver wiring diagram. I realise there are many videos of relay driven. An ignition coil or spark coil is nothing more than a low frequency auto transformer with a relatively high turns ratio. As the basic of this laser diode driver this circuit uses a howland current pump with a current booster. It is very comparable in design to the pulse transformers used in other appliances such as fence chargers well suited for high voltage bursts.
This video concentrates on coils from an electronic point of view and reading wiring diagrams. 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. I checked continuity in the coil driver wire from the 4 cylinder coil connector to the pcm and there is continuity with no resistance. The coils which are the basis for ignition coils and alternators have very specific electronic.
So the coil driver wire seems to be fine. Ignition coil distributor wiring diagram size. Compared with a a switched pwm drivers this simple linear laser diode driver provides cleaner drive current. Here is the schematic diagram of the circuit.
