nick260890 Posted June 18, 2013 Share Posted June 18, 2013 ive got a x-line oil pressure gauge, the ones tuning developments sell, I went on holiday for a week and came back and noticed its not working, it lights up, just the needle doesn't go round to tell what pressure there is, it occasionally works and then doesn't, ive checked the wiring to the sender unit and its all okay, any idea's??? cheers Quote Link to post Share on other sites
Broony Posted June 18, 2013 Share Posted June 18, 2013 bad earth? sticky sender unit? bad connections?? Quote Link to post Share on other sites
nick260890 Posted June 18, 2013 Author Share Posted June 18, 2013 there's earth there, 2 wires going to the sender, one goes straight to earth and the other wire is the signal wire that goes to the gauge, which is also earth, im guessing the signal wire works by reduced voltage?
