my oil pressure gauge is not working, any idea's

[nick260890]

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

bad earth? sticky sender unit? bad connections??

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?
