2.25 petrol B reg SWB pickup.
The Smiths trip meter does not work. The speedo works fine, the mileometer works fine. The trip meter gets to 40 and then makes an annoying clicking sound. This goes on reset back to zero. The dials for 1/10 and miles does not move as far as i can see. 40 comes up after about 2miles.

Tripped mine to zero and the fooker never moved again! Swapped it in the end
