The glow plugs have an internalresistive element that increases in resistance as it heats up. This protects the glow plug from overheating byreducing the current flow as it gets hot.Whenever the key is turned on, the main machine controller tells the control panel to display the “glow plugson” icon and sends out 12 V from connector J3 pin number 32 to the glow plug relay winding. Since the otherside of the winding is connected to ground, this energizes relay which in turn supplies power from circuitbreaker 11 to the glow plugs. After approximately 10 seconds, the main machine controller de-energizesthe glow plug relay by removing the 12 volts from the winding which also removes the power from the glowplugs.
