speedyg 16 Report post Posted February 17, 2006 The temp gauge in my car seems to have a bit of a mind of it's own. I suspect it is a dodgy earth. It works fine while the car warms up but when it has reached normal temp it then starts creeping up until I look down and tap the dash, then in goes back to normal. Lately it seems to jump up and down all over the place between normal and high. I have unplugged it and cleaned the connections but no change. Do I just splice in a new earth? Any ideas? Thanks Quote Share this post Link to post Share on other sites

Guest Spargo Report post Posted March 4, 2006 Did you tighten the connections to the actual gauge behind the dash? Quote Share this post Link to post Share on other sites
jochen 4 Report post Posted March 27, 2006 You batteries will be knackered. The dash has a rechargable battery on board, so it never forgets the last speedo mileage etc. The battery fails after some years, giving your symptoms. Easy to replace - it is soldered in. Jaycar can supply good replacements. Jochen Quote Share this post Link to post Share on other sites
