    Basically i want to try and create a simple ignition driver circuit that utilizes a function generator to control the circuit. And i know that there is a high level of kickback involved with an ignition driver.

    So basically I'm trying to get this done as simple as possible.

    1) Use a function generator to drive the Ignition coil
    2) use an opto isolator to isolate the high voltage circuit from the Function generator

    And just kinda to start off i was thinking of using the output signal from the opto to trigger a transistor (2n3055 since i have spares of these) And the transistor will act as a switching device for the ignition coil

    However, i don't seem to be able to get the circuit to work. So any advice/schematic on how to proceed would be nice.

    Go to a junkyard and give them $2.00 for a "4 pin HEI module". Google "HEI" and see how to wire up the module. It will show the input to the module being fed from a reluctor. Do not use the reluctor, hook up your function generator in place of it. Fire it up and watch the sparks fly.

    We do not want highvoltage circuits over here.
