hello everybody
my ques about the fuel injector,which is working electronically--
i saw it for real in a car was fixing by a mechanic,and i looked at the electronic fuel injectors mounted on the fuel rail----and while the engine was running,the injector as u know-is supplied by the pressurized fuel from the fuel pump through the rail to the injector and its controlled by the ECU,to calculate the pulse width-,anyway my ques is completely imperical-:)--
i found two wires installed in every injector----what are these two wires?
when i removed it and came with a lamp and while engine was running i installed the two wires i took from the lamp in the cable comes from the ecu to the injector,the lamp turned on-and when i reversed the wires it also turned on--!
before i do this test ,i thought one wire is the vcc-(electricity feed)to the injector-and the other is the ground
now-im confused-cuase to make the lamp turn on it must connected to two terminals(one is positive and the other is negative which is a ground)
that what i was thinking,but i don't know if I am right-cuase I am not good in electrecity or electronics-but i know a little
i want to know how can i test this injector?with avometer?to check if the ecu already send the signal to the injector to work or not.
thanks for any help
