water temp light flashing shortly after startup , on corrado

[james_c2 0]

went to go for a drive last night and just after i started my engine (about 20secs or so) the water temp light above the gauge started flashing, started it this morning and same thing again

 

i take it this is prob down to dodgy sensor in expansion tank? also noticed the brown wire from the sensor had worn thu and touching the coil, ive re wrapped this, is there anykind of inline fuse that could of blown because of this???

 

cheers james

i think when theres water across the sensor it joins the 2 connections, and they are earths. If the wire was touching metal work it shouldnt make a difference. Try undoing the plug at the bottle and joining the wires toegther, this should turn the light out
