I have recently bought an oil pressure gauge and I am trying to wire it.
It is an all electric TIM oil pressure gauge.
It has 3 terminals with at each terminal the letters O C and G.
Does anyone know what these letters stand for in the electric terms so I can understand them.
I have been trying for hours to google these gauges and not 1 has these letters.
I have been intouch with the lad who I bought it from and he sold it on only because he didn't know them either.
Please help if you can.
Thanks
Mick
Cant find much either.. but you could always try :

The manufacture will know.
The other way is to see what country they are made in, then google translate words like Ground, Positive, Signal etc and see if the words start with
those letters....

Most of these gauges are moving iron, very low cost and reliable. They have two coils connected to +ve via two resistors (I think if I remember correctly). The sensor is placed in parallel with one of the coils thus unbalancing the bridge arrangement and changing the current through one of the coils. The wisdom of these words can be evaluated with a simple ohm meter. If we assume the G = gnd then measure the resistance to the other two terminals. If I am correct the resistance will be larger to the positive terminal than the sensor terminal. If you want to measure the terminals then we can continue the debate and adapt my theory. The application of a digital ohm meter will damage nothing. Enjoy!
Thanks for that info. I will try it out next week after easter. If I had my way it would be tomorrow morning, but you know what the women folk are like!
I have two daughters and a wife of course and even the cat is female, what chance do I have!!!
I have 2 daughters of course the Mrs a son who I am helping with his track car[ trying to follow in his dads footsteps ]
and 5 grand chidren.
And you think you have no chance. I'm on the crusifix bleeding
