Paul H Posted September 18, 2017 Report Share Posted September 18, 2017 (edited) Fuel Gauge slowly goes from say 1/2 full , to reserve or empty . All very graceful indicating im dropping fuel everywhere and initially very disconcerting !! . After a period of time say 10 mins its climbs back up but not to correct reading , goes back down again , then climbs back to normal . This doesnt happen on short journeys and generally after 20 miles . Because of the graceful way the needle drops I dont think its a cable issue - In the last 300 miles its only happened twice Incidentally the temp guage is an aftermarket and works fine Any ideas Paul Edited September 18, 2017 by Paul H added text re temp guage Link to comment Share on other sites More sharing options...
Pete Lewis Posted September 18, 2017 Report Share Posted September 18, 2017 check the sender earths on the tank check the output from the voltage stabiliser, check its earthed ok on the speedo its normal for the needles to move slowly . as the are damped by the bi metal operating spring, any break in supply gives a quietly descending needle the sender may also have a fault in its windings , when the tanks low remove it and test the readings with a multi meter set on resistance 1 Link to comment Share on other sites More sharing options...
