Water in fuel alarm

[Philip]

So I started to get a water in fuel alarm on my port engine but not the startboard.

1. Immediately checked fuel samples of both sides by draining primary racor into a clean glass jar – no water noted either side.
2. Changed primary racor filter with new 10 mic filters
3. Changed on engine FF5488 with new filters and dumped contents into glass jar – no water noted either side.

At this point suspect either bad sensor or harness wiring.

1. Do sensors go bad?
2. Best way to clean sensor

Next step is to remove sensor and clean and disconnect all connections to confirm no corrosion and good connections. Any other advice??

Thanks

Phil

Most likely just a glitch.. Clean connections on the end of the WIF sensor, spray all wire plug connections w/ WD-40 at all plugs, and see where it goes.. Remember, this is “SmartCrap” stuff .. Glitches are part of why Cummins has walked away….

Do the resistors go bad?
