How do you test resistance on glow plugs?
To test the resistance on glow plugs, first, disconnect the glow plug harness to ensure no power is flowing. Use a multimeter set to the ohms (Ω) setting and connect the probes to the terminals of the glow plug. A healthy glow plug typically shows a resistance reading between 0.5 to 2.0 ohms; if the reading is significantly higher or shows infinite resistance, the glow plug may be faulty and should be replaced. Always refer to the manufacturer's specifications for the exact resistance values for your specific glow plugs.
Is there a test to see which glow plugs may not be working?
This test will determine what glow plugs are working. ( It will not determine a partially burnt plug ). Disconnect the glow plug wires at the plugs .( You must unplug all of them for this test to work ) Connect a test light to the positive terminal of the battery. Touch the electrical connector at the end of the glow plug with the test light. If the light goes on the glow plug is working. Make sure you touch only the electrical connector on the plug. If you touch any other part (metal) of the plug the test light will light giving you a false reading.

How do you test glow plugs?
To test glow plugs, first, ensure the vehicle's ignition is off and disconnect the glow plug harness. Use a multimeter set to the ohms setting to measure the resistance across the glow plug terminals; a reading between 0.5 to 2 ohms generally indicates good functionality. If the reading is significantly higher or shows infinite resistance, the glow plug is likely faulty and should be replaced. Additionally, you can perform a visual inspection for any physical damage or carbon buildup.
How do you test glow plugs on a 6.0 liter?
The best way that I have found to test the glow plugs on anything is with a simple ohm meter.

You should have a tolerance to be between. If you Are not there, odds are its bad
