Glow Plugs
Glow plugs are small 6-volt heaters operated by the Electronic Controller. Glow plugs cycle on and off, powered by 12 volts to give rapid heating. Glow plug light on dash should illuminate as plugs cycle on and off.
Glow plugs cycle for approximately 25 seconds with ignition on regardless if engine is running or not. On and off cycling varies with system voltage and temperature.
