will be verified during the engine installation audit.
6.1 Water In Fuel Switch
6.1.1 WIF Switch Operation
The water in fuel switch indicates when the fuel filter bowl is full of water.
During normal engine operation the switch is immersed in diesel fuel. As
water collects and reaches the maximum level the water enables a conductive
path between electrodes (normally open switch). The WIF switch is supplied
assembled to all engines and is a mandatory installation item. The electrical
connection of the switch to the engine ECM is the responsibility of the
customer and should form part of the machine wiring harness connection to
the ECM J1 connector.
