Abstract: A secondary ignition voltage peak meter provides an indication of ignition operation. A capacitive sensor picks up secondary ignition voltage, and an inverting amplifier reduces and inverts that voltage to a second signal. The second signal is conducted to first and second signal storage circuits and is respectively stored as third and fourth signals. Signal from the second storage device is provided to a second amplifier and converted to an on-off gating signal. The signal from the first storage device is provided to a first power terminal of a field effect transistor, and the gating signal is provided to the gate terminal. A third storage device is connected to a second power terminal of the FET, and a third amplifier is connected to the third storage device to provide an output which is moved by a capacitor and adjusted by a potentiometer. The output signal is delivered to a display driver, and the display driver converts the signal to a sensible signal of good, fair and poor ignition operation.
