To test the glow plug controller on a 6.5L diesel engine, begin by ensuring the engine is off and the ignition is in the "off" position. Use a multimeter to check for voltage at the glow plug controller terminals while turning the ignition key to the "on" position; you should see voltage indicating the controller is functioning. Additionally, inspect the controller for any visible signs of damage or corrosion. If the voltage is absent or the controller appears faulty, it may need to be replaced.
The control relay is at the rear of intake manifold.
The glow-plugs are located under the valve covers. There is a single wire that comes out of each injector harness that powers each glow-plug. Disconnect the single wire from the glow plug. Connect the gator clip of a test light to a positive and probe the glow plug terminal with the test light. If test light does not come on the glow plug is bad.
