Why does my glow plug light up when I start the engine?
If the test light lights up, the plug is receiving power. Evaluate whether or not the relay is able to supply the power required to start the diesel engine by testing the ohms of the circuit with an ohmmeter. A working relay will produce between 50 and 120 ohms. If the circuit is producing less than 50 ohms, the relay is suspect.
