Apply Alodine to the connector header shell contact area in accordance with the
Alodine manufacturer’s instructions. Allow the Alodine to dry.

Clean the connector header face with mild solvent. Inspect for contamination.
CAUTION: Do not directly apply liquid cleaning agents to the
header as the pin socket may fill with fluid. Sparingly apply cleaner
to cleaning cloth.
7.
Inspect the engine low voltage harness connector for contamination, deformed pins,
or any observable discrepancies. If the old seal is observed at the base of the
connector pins, remove with tweezers.
8.
Check the resistance between the connector(s) header (Figure 10-48) and airframe
electrical ground. The resistance must be less than 0.5 ohms.
