... When the system is running on the ignition module, that is, no voltage on the by-pass line, the ignition module grounds the Electronic Spark Control (EST) signal. The ECM expects to see no voltage on the EST line during this condition. If it senses a voltage, it sets Code 42 and will not go into the ...

Electrical ballast



An electrical ballast is a device intended to limit the amount of current in an electric circuit. A familiar and widely used example is the inductive ballast used in fluorescent lamps, to limit the current through the tube, which would otherwise rise to destructive levels due to the tube's negative resistance characteristic.Ballasts vary in design complexity. They can be as simple as a series resistor or inductor, capacitors, or a combination thereof or as complex as electronic ballasts used with fluorescent lamps and high-intensity discharge lamps.
