Hi there
i am doing an installation for a EGT sensor with amplifier in a G4x. The Amplifier has 3 wires, power, ground and signal, and also the shield.
My question is... i assume the system will be at sensor ground instead of chassis ground...but what do i need do with the Shield? connect the shield to sensor ground also, or chassis ground or leave it ?
l sold another of that amplifier to a customer and sensor is reading good with is outside the manifold, but when he conects the sensor to the manifold, (and obviously, chassis ground) the sensor reads 0. Something with the shield would be wrong or may be with ground but i want to be sure the best way to avoid more problems like this
