Finally got around to sorting this today. First had to redo the mod that CC had done, they had wedged the twisted cable ends into the connector pin and stuck with sealant, proper job? All came out when we had to disconnect it when car stopped on the Italian tour due to failed rear wheel sensor. Soldered the cable in then refitted connector and adjusted sender to same gap as the previous one. Test drive gives a flickering needle up to 55-60 then settles to rock steady as speed increases. Mileage recording is way out too, recorded about 12 miles on approx 25 mile drive. So, have I messed the earthing up or is the adjustment still not right? All ideas gratefully received, this is driving me nuts, 5th sender in 4 years! Thanks, Garry
