Vincent Moy Posted July 20, 2009 Author Share Posted July 20, 2009 give the oil press orafice a poke might be sludge in there!! I asked the same Q. on xjbikes forum and the people said the wire is probably broken. My question is if the wire is broken isn't it shouldn't send any signal to the lite at all no matter it's gnded or not? Link to comment Share on other sites More sharing options...

All can think of is you have an earthing issue which will make the circuit drewps Link to comment Share on other sites More sharing options...

I don't know how all this works. BTW, the oil pressure switch is NOS from ebay. Link to comment Share on other sites More sharing options...

And I don't think the wire is earthing out because if it does then the light should be on all the time. So somehow the switch is not connecting (normally when there is oil press.) even when there is no pressure at all, like when the bike is off. Does anyone knows how to test an oil pressure switch?

plain old dave Posted July 22, 2009 Share Posted July 22, 2009 give the oil press orafice a poke might be sludge in there!! Seconded. If you have good wires, good bulb and a clear passage to the switch, you got a defective switch. Link to comment Share on other sites More sharing options...
Vincent Moy Posted July 22, 2009 Author Share Posted July 22, 2009 Seconded. If you have good wires, good bulb and a clear passage to the switch, you got a defective switch. When I unscrewed my old switch, there was oil coming out. Plus if I have a blockage on the passage and assume the switch is working properly, shouldn't I have the light on all the time?
