connector (component code 365, 191, 366, 189, 190, 192) (broken, oxidised, bent tabs).
If the connectors are faulty and if there is a repair method (see Technical Note 6015A, Repairing electrical
wiring, Wiring: Precautions for repair), repair the connectors; otherwise, replace the wiring.
Check the insulation, continuity and the absence of interference resistance on the following connections:
