scott_prelit now westfield_bumble Posted April 2, 2008 Share Posted April 2, 2008 Having problems getting a reading from my speedo. Its an acewell unit. Uses hall effect. Checked distance between magnet and sensor and its under the 8mm max as in instructions. Is there anyway i can check if its sending a signal to the input of the speedo. Any other things i can check. got me mot friday and will be a bit suss if i drive there and it still says zero miles. Quote Link to comment Share on other sites More sharing options...
pistonbroke Posted April 2, 2008 Share Posted April 2, 2008 The signal from the sensor will be microvolts, much to small to measure by normal means . Is there a 12v feed to it from the speedo ? Also make sure the surface isn't contaminated , It could effect the magnetic PU As an afterthought , the speedo isnt a requirement for MOT neither is the oddometer afaik Quote Link to comment Share on other sites More sharing options...
scott_prelit now westfield_bumble Posted April 3, 2008 Author Share Posted April 3, 2008 Only 2 wires go to it. Think i might solder the joins instead of a connector as wire is very thin. Fingers crossed for tomoorrow then Quote Link to comment Share on other sites More sharing options...
