tachometer connection

[acenie]

paano ba yung connection, i have already a tachometer 4 wires, how do i connect it to the engine, if the engine is diesel

[SunTzu]

red wire = main power (ignition)
black = ground
green (tach or shiftlight) = rpm from box

in the injection pump area have 2 wires, so where to connect this?
to the tachometer?

I have no idea sa diesel na ride...pero if you have a multi tester, check mo kung alin dun sa 2 wire na binangit mo ang ground...yun ang sa black, and the other sa green wire.

I tested the sensor(injection pump) but no one is connected sa to a ground, so meaning yung isang wire baka connect to +12V and the other one is to the tachometer. ito kaya.

possible din yan. Try setting the multi tester to volt (sa 50V max) and measure the voltage across the 2 wires, then one of the wires and a body ground....if you get a reading on one of the wires, yun ang live (12v+).
