BROWN: Use to connect to the fuel solenoid valve. BLACK: Use to connect to the temperature sensor.Installing the Warning Decal(s)
Two 8T2930 decals are included in the group:
Example of the 8T2930 decal installed close to the engine's 9L6531 Engine Information Plate.* Install one in a VISIBLE location in vehicle cab .. and* Install one in a VISIBLE location in engine compartment or on engine.Operating the Intake Manifold Heater
This portion of the instruction will explain the operation of the intake manifold heater and a basic explanation of how it works.A few moments spent learning the sequential steps required to engage the system, and a reasonable knowledge of the components functions during cranking, will allow the operator to start the engine in a minimum amount of time.Procedures to Start the Engine
Switch on (RUN position) the main key operated switch:* The indicator light MUST light up and stay on for the duration of heating process.* This will start the (40 - 60 seconds) heater plug preheat mode. The heater plug will start to heat as soon as the switch is activated (RUN position). The heater plug will soon be too HOT to touch.The preheating process is voltage dependent, refer to the Corrective Action column in the Troubleshooting chart.* The preheating process will last 40 - 60 seconds (depending on the voltage).* Upon completion of the preheating process the pilot lamp will go out.* The engine can now be started.Start the Engine
The engine must be started:As soon as the engine starts:* The indicator light will light up again for the entire duration of the inlet manifold heating process.* Not later than 30 8 seconds AFTER the indicator light goes out .. and* The alternator MUST reach charging speed.If these two requirements are NOT met:* The intake manifold heating system will be switched OFF automatically.This happens when the alternator does not provide a signal to the D+ terminal of the ECM.If this occurs:To restart the engine the main key operated switch must now be:* Switched OFF for several seconds before attempting to start the engine.When the main switch is switched on (RUN position) again:* The pilot lamp will light up to indicate the start of the preheating process.The engine can be started as:* The pilot light goes out.After Engine Start
After the engine is started:*
