Title: current flow to a diesel injector
Post by eff511 on Mar 5^th, 2009, 3:09pm

hi all does anyone know what voltage i should have at number 1 injector on a 1998 2.5td? on tickover i have 12v on one side and 0.2 v on the other

On some petrol engines the injectors are operated via a ground signal from the ECU and have a permanent live when the key is switched on,a sensitive meter could show a small voltage on the ground side.Diesels I would not be too sure on,but the principle would be the same on an electric injector in both I would have thought.A VM expert will pop up I'm sure.

the vm expert is what i am hoping for or someone just to do a check on another 2.5 td i managed to do it as i do most voltage tests is by separating the plug connection and popping wires into the one end and the other end of these wires i have i have put small insulated crocodile clips which you can clip on to the pins and then test from there hope this might also be a useful way of testing for others instead of stripping wires or trying to pierce the wires cheers kev
