Conduct electrical test of glow
plug (see Section 5.7, Fig. 504,
Point 6):
Measure glow plug resistance on glow plug connector
X5 (white wire), also see Section 9.3.1
At 25 ± 5 °C:
0,235 to 0.355 ohms
Unfortunately you will have to remove the heater to replace the glow pin. It is usually advisable to replace the burner tube with burner pad at the same time if it has had a lot of use.
Also, sadly, I have sold out all my stock of Evo burners with glow pins - I was selling them off at half price.
