tempreture gauge

[jpliddy]

hi all my temperature gauge is playing up .
it moves to about 11 o clock as soon as i start up
i disconnected the suppy to the engine today its to the left of no 1 injector
but no change it still goes on and moves to the same place so i take it the temperature sender from the block is not to blame .
if its the clock my fuel gauge plays up to going to full always when not full
i have renewed my circuit board with a new one a few years ago so can't be that .
any help much appreciated
