Abstract
The subject matter of this specification can be embodied in, among other things, an internal combustion engine ignition system includes a voltage divider configured to be coupled to a primary transformer ignition coil connector, the voltage divider configured to reduce a voltage received from the primary transformer ignition coil to a controller voltage, a comparator circuit with an input coupled to an output of the voltage divider, and a controller configured to detect the voltage output of the voltage divider, detect the voltage output of a vehicle electric power supply, detect the voltage output of a comparator, and determine an estimated breakdown voltage of a spark plug based on the detected output voltage of the voltage divider and the detected voltage of the power supply.
