Examination
1. Check the resistance of the glow plug between the contact and the glow plug body as shown. Resistance: 0.25 ohm.
Warning! Before measuring the resistance, remove any traces of oil from the glow plug, as the resistance of the glow plug is very low.
2. Check the voltage supply rail to the glow plugs for rust.
3. Check the glow plug for damage.
