Primary Fuel Filter Water in Fuel Sensor

[1doodadd]

Every System will have a Primary and then the Secondary. If it does not Put a Primary on. I have a 2000 Beaver Marquis Amethyst with the Raycor primary water fuel filter. Check out the provided pics. Ayn ?'s get back to me. The first pic is my purge system I can eliminate air out when replacing the filter and purge and water as seen on the panel



I don't know how the Secondary filter got mentioned on the first and second post when the original question was about the Primary Filter Wire

Ken,

The following pictures show the labeling on them. Normally, they will have an alphanumeric label so you can trace it back to front run panel. These just use WIFA and WIFB in front of the wire descriptor.

I thought I would look at the dash for "water in fuel" light to see what the wire labeling was there. I have no such dash light. Next was to turn key on, engine off and watch lights. WARNING light comes as bulb check and goes off. I unplugged the wire connector at the fuel filter and do KOEO test again and light WARNING goes off. Next I short the wire in the connector together and once again do KOEO test and WARNING light will not turn off.
I have most of the wiring diagrams and the water in fuel circuit is not among them. Nor, do I have back of dash wiring, like I did on last coach.

It may just go to the ECM, but not positive. My fan controller wires say "ECM FAN SIGNAL" & "ECM FAN RETURN" leading me to believe that I'd the went to ECM they would be labeled as such.

My 2 wire harness originates it the spaghetti mess of wires on top of the frame and leaves the mess behind the gray rear run box and above muffler. Mind you, I have an 2006 ISL in my 2008 coach, making it a little different than yours.

Do you have a WATER IN FUEL light on your dash?

The mystery continues!

Yes have water in fuel light on the dash. I believe I have the Medallion message center system.

Attach is photo of primary filter (white) located on driver side of engine and secondary filter (yellow cat 2 micron) on passenger side. Also message center in dash with water in fuel light on when key first turned on.

Thx for taking the time to help me research this.
