Steviekid Posted February 20, 2005 Share Posted February 20, 2005 Hi everyone, I've just bought an Import Supra and have fitted a kph-mph/delimiter chip to the back of the speedo. It works fine except under hard accelaration when the speedo needle flicks up and down a lot. Once I settle on a speed it reads ok again. I've also noticed that it flicks about when you press the windscreen wash buttons etc when the ignition is on but the engine isn't started yet. All the connections are secure enough at the back. Any ideas?! Link to comment Share on other sites More sharing options...
Whitesupraboy2 Posted February 20, 2005 Share Posted February 20, 2005 Hi mate, its a bad earth by sounds of it, i have very similar problem. Speedo fine....turn lights on and it goes a bit nuts like urs or sometimes dies all together. So i have got a dodgey earth connection for Dash lights. Also if im sat with it idling and flick lights on...the needle *blips* is best i can describe it. Dangerous Brain on here had same problem with old car, went funny or died under accelaration, was a bad earth on his too. Link to comment Share on other sites More sharing options...
