The car is from 1988. I quite sure that in some diesel cars revolution is measured in alternator. The voltage frequency is proportional to revolution. In this way revolution it's measure in e.g. VW or AUDI, but i'm not sure what it's measured in Volvo.

I don't have a tachometer in my car. Now it's only Clock and speedometer. I try to find a diagram a tachometer in diesel. How revolutions was measure. From alternator or in another way???
Please help me!

cheers

I have small problem with wiring ... previous owner those car , mix somethig in wiring:
1)When do you switch the interior light you don't have any chance to start car (no ignition). I think it's a kind of simple alarm.
2) If you open glove box (glove compartment) the interior light to be on ...

it works with a turbine i think. i also think that the diesel may run at to high pressure to let the system run properly, but i may be wrong.

high pressure is behind injection pump but before it's not so higt. The fuel is supply and excess come back to the fuel tank. It's a easy method to measure ...

OK.
I try to find something about how works sensor in the fuel line. I have Volvo Diesel (;( - it's doesn't demon for speed ... he he ) and i'm interested in measure fuel ....

Maybe somebady come up against something about that in web?
