6.4.3 Glow plug component
See Fig. 904, Item 6
NOTE
The resistance test must be carried out with an ohmmeter
suitable for small resistance values.
A resistance test with a simple digital multimeter is too
inaccurate to find the precise values. A new glow plug can
be measured to act as a reference.
The glow plug should have the following values in the test:
Glow plug: 12 V (red) 24 V (green)
Resistance at
25 °C: 0.263 - 0.323 ohms 1.125 - 1.375 ohms
Test current: < 5 mA < 5 mA
