ive notice my temp gauge doesnt budge off the bottom. it was initially going into the red with gentle use but now barely if at all gets off the mark. is there a relay or fuse? i recently shorted the fuses inc the dash instruments but replaced the fuses and everything is working except the temp and the rev counter. any ideas? cheers in advance

 

Don't think there's a fuse or relay mate. Try disconecting the sensor wire and putting the wire to earth, sensor is on the head on the right hand side, then switch the ignition on and see if the gauge moves, of so it's the sensor that's had it
