Smartcraft fuel/water warning setup

Phil M · 14 September 2015, 16:55

Following on from my expensive first service, I have a Mercury Smartcraft setup question. I have a mercury fuel/water separator with sensor. The instructions detailed how to fit it and it came with a harness to connect to the "tank 2" connection on the smartcraft accessory harness. What it didn't include and I can't figure out is how to set up smartcraft to see it as a separator warning and not a tank level. Any body got any ideas? I suspect the service center has just charged me £150 and not sorted it.

Have you tried to find the operations manual for smartcraft online, I downloaded one a few years ago, it's out there

I have the paper manual that came with it. Sadly it doesn't cover it.

Thanks Whiskylee. Unfortunately its the same as the manual I have. It mentions the warning as being a feature but no mention of how to set it up/enable it.

This is the later manual but it still doesn't say how to 'enable' the sensor reading. The installation sheet simply says connect the water sensor to 'tank 2'(blue wire) of the fuel/paddle wheel sensor harness (tank 1 is fuel level)
I am hoping this is then a default that the smartcraft knows ??
Did you solve the query as I am just installing mine - with the dealer ( and maybe he will know when I go back tomorrow !)

I am also unsure of the fuel used 'calibration' - seems complicated and relies upon the fuel sender ??? On my Optimax I am replacing, it was a straight reading from the ECU and very accurate. The calibration of the fuel level sensor was only to try and get the fuel contents gauge to read something close to reality and nothing to do with usage. The readout was a nice miles/litre ( distance coming from the GPS)
Have you worked this one out as well ? ;-)

I had a dealer look at it on its first service and they implied that it just did what it was supposed to without setup. I am not sure that I believe that so keep an eye on the fuel filter anyway. If you get a sensible answer, please let me know.

As for the gauge calibration, that is only for the fuel tank level meter. The fuel used, l/mile, l/hr etc are all set up ready to go and do not rely on the gauge at all, as per your old engine. I tend to use the level as an indicator but brim the tank every once in a while and go on fuel used since last reset. I believe if a gauge and GPS are connected it will tell you a range in miles left in the tank. I really must get around to connecting this at some point.
