![]() ooh yes thatd be problem one the original oil pressure switch is just a switch the sender will change resistance according to pressure what you need to do is use a tee so you can fit the switch and the sender and wire both up as for the temp disconnect the wire and earth it to the block this should make the gauge read highest temp if not you have somat else wrong

![]() I think you misunderstand Andy Ray, He has the preasure switch and a T-pice to the senders for the preasure and temp.
Perhaps these are back to front Andy? TT

![]() My oil pressure goes off the scale when the oil is cold and thick, once it warms up its about 25psi idle and 80psi on the move
I thought i had it wired wrong when it initially went off the scale but i let it warm up to see what happened, maybe you need to do the same before you change any connections Also oil temp guages take ages to get a reading as oil takes quite a while to warm up to temp, a good few miles of driving after the coolant temp is up to normal. It will prob take quite a while to get the oil temp up just revving it stationary compared to being under load when driving along |

![]() As it was pouring down, I kept the car in the garage when fitting the gauges, tho I did let it run up to temp ( coolant). Hopefully if weather is kinder tomorrow I,ll have the car outside & will give it some welly .....stood still ![]() ![]() cheers andy |

![]() Sounds like a bad earth to me Andy. I've got a water temp gauge that was having the same problems, all down to the earth on the sender.

![]() Hmmm, the senders I have don,t have an earth, the gauges have an earth & in the instructions it says " Direct to engine ground" from a terminal on the back of the gauge, which I have done
![]() Now you can see why I had an auto electrician wire up the major part of my cars wiring ![]() Tho, I had success yesterday....successfully wired in the reverse light, fog light & the fuel level gauge...all working as should be ..... I can now tell how much fuel I have ....yeehaa ![]() cheers andy |

The block is your earth, so unless your ( t-pice, oil manifold, sandwich, whatever ) is an insulator then so long as your engine is earthed then the sender will be too. TT
