whats it measuing, air or water?
check the earths at the gauge and some of the autogauge sensors need to be earthed so check that too.

check the earth on the gauge then check the sensor. some have 1 wire and some have 2.

if its 1 wire it uses the earth body return system if its this try running a new wire from the - Batt to the metal part of the sensor to see if it kicks it into life

Jeez,

I think it comes from a small sensor on the underside of your rad top pipe (can you check where the sensor is on the coolant - this is from memory) it runs round the side of the bay past your catch tank and through the bulkhead, trace the wire and have a look if there is any damage, or check your earth to the gauge.

I am just looking at some hi res photos of the Boris' bay...;)
