Drying wiring harness
If there is any oil or dirt on the wiring harness,
wipe it off with a dry cloth. Avoid washing by
using steam. If the wire harness must be
washed in water, do not apply high pressure
water or steam directly to the wiring harness. If
water gets directly on the connector, do as
follows.
1. Disconnect the connector and wipe off the water
with a dry cloth.
a If the connector is to be blown with dry
compressed air, there is a risk that oil in the
air may cause defective contact of the
conditioner, remove oil and water in the air
before starting air blow.
2. Dry the inside of the connector with a dryer.
If water gets inside the connector, use a dryer to
dry the connector.
a Hot air from the dryer can be used, but
regulate the time to use hot air in order to
prevent the connector or related parts from
becoming too hot, as it causes deformation
or damage to the connector.
3. Perform a continuity test on the connector.
After drying, leave
disconnected and perform a continuity test to
check for any short circuits between pins caused
by water.
a After the connector is completely dried, blow
the contact restorer and reassemble them.
