why does this keep coming on?

[whiskers]

hey everyone It's been a long time since I posted here sorry about that but life gets in the way sometimes.

Anyway I hope someone here can shed some light on this for me, latley when I first start the car a 99 forte sedan (cold start) this light is flashing at me it has been doing it since new, I have taken it in to ford (under warrenty) sometime ago but was told that it isn't hooked up to anything, also I had a look in the service book that came with the car and looked up to see what the symbol meant, it's for the low level water for the water cooling tank or so I was told I know that this model hasn't got the connections for the tank, I have fitted a new tank a few years back and there is defineatly no wires to connect a sensor to.

The car is getting hard to start since this light/symbol has been falshing at me, the car seems to hesitate and then catch like a flat battery or battery going flat but I know the battery is ok. the attached pic is with the car running I had just started it.

Any and all help will be very appreciated.

Cheers and thanks
