the wire to the sender, if it touches "earth" (any part of the car) will result in the gauge going to maximum (the sender is a resistor varying the connection with the temperature) so, either your wire is shorting to earth (test by removing it off the sender, if it isnt touching earth or the sender the temperature gauge shouldnt move, if it does you have a short to earth, if it doesnt then your sender is buggered
Something (not sure what) has been happening to the cab for the last week or two! 1) If I keep my foot on the brake whilst stopped a constant low level buzzing comes through the intercom system 2) A low level buzzing in general coming through the intercom whilst switched on and travelling 3)The radio (music etc) seems to be picking up interference/losing the signal more than usual 4) Once or twice the headlights have gone off and back on when I have used the signal stalk, and last but not least the headlights have not come on immediately - but a split second or two later when switched on.
My first thoughts re the buzzing and the cab radio (music) were that a suppressor had come off/broken/loose. It would appear to be a bit more than that.
