Inspection of Glow Plugs
In order to check the heating coil or element, measure its resistance as shown in the diagrams (right) and based on your findings if;
- Resistance value ∞ : The heating coil/element is broken
- Resistance value of a metal glow plug is less than 5 ohm: The heating coil is in good condition.
- Resistance value of a ceramic glow plug is less than 1 ohm: The heating element is in good condition.
