Glow plugs on some older diesel engines work on a 6 volts current and a dropping resistor reduces the voltage from 12 to 6 volts. The glowing period lasts 9 seconds and a 1,652°F “Quick-Start” pencil element temperature is attained. The top temperature rises to 1,976°F after 30 seconds.
There are 4 glow plugs per cylinder. GM – General Motors offers 4 glow plugs per cylinder in medium- and heavy-duty versions of the Duramax diesel engine, with six cylinders total. Light duty versions use 5 glow plugs per cylinder for a total of 30 plugs for a 6.6 liter engine, and 18 per cylinder for a 3.0 liter version, for a total of 54
To make starting a 4000 series tractor easier in cold weather put the range selector in gear and turn the key to the start position and hold it there for 5 seconds or so.
