"Think about it, if the wire is isolated ( why you disconnect both the processor and injector, the wire is now open at both ends ) and you show continuity you have a short too ground don't you?
Uh, no. It shows I have one continuous piece of wire.
If I have what sould be one continuous wire and I ohm it out and determine it to be "open", I have in fact two pieces of wire held together with insulation.
It would show a short to ground if I held one lead of an ohm meter to one end of the wire and the other to a chassis ground or something not supposed to be connected the unconnected wire.

| | That's correct. Isolating the ground wire from the circuit. If there is even an | hint of continuity you have a short. You can even call it a closed or complete | circuit. The wire is grounded to something that makes a path to source. He just | got his answer fast easy and accurate.

| | If he needs to have that explicit instructions he should not be doing this, | period. | | "Think about it, if the wire is isolated ( why you disconnect both the processor | and injector, the wire is now open at both ends ) and you show continuity you | have a short too ground don't you? Why then would you replace the processor? You | would not, you would find the short too ground on the wire! If you do not have | continuity you have an open circuit, which is exactly what you should have! The | processor is now suspect." | | Notice "( why you disconnect both the processor and injector, the wire is now | open at both ends )" even you should understand that. If he does not know what | to do with the wire at that point he is way over his head. Obiviously by this | staqtement, you are as well....."if it's 'open' (no continuity), then he cannot | (by definition) 'test for a short', since the open would prevent any possibility | of seeing the short, since the meter is now disconnected from part of the | wiring (the part that he 'made an open'" | | I told him to isolate the wire and test it for a short, I should not have to | tell him how. I'm not going to hold his hand or yours. I'm glad I did not tell | him to seperate connector # C147F that would have just made things worse. | | | | > >

| | Not only do I know what pin, I know the color. The color by the way is a clue on | how he can find it, but like you that's over his head. I also know where to go | to find the pin location, one of the things one needs to know in diagnosing | electrical problems. #6 ground wire color is LG/O. #1 is T oh I'm sorry, LG/O | would be light green / orange T would be tan.
