smokin' joe Posted August 3, 2012 Share Posted August 3, 2012 are you using correct sender unit? maybe need to check earth connect to head of engine?? Quote Link to comment Share on other sites More sharing options...
azzurro Posted August 3, 2012 Share Posted August 3, 2012 just installed one in mine, was easy peasy. if it is 100% mechanical you can check it works by putting the sender it in hot water. It takes a while for the tip to warm up and eventually register on the guage. Could just be a dud if it never worked, or maybe needs a bit of 12V to work? Photo of the back?
