when checking for spark ,
what part of the spark plug do you allow to touch the valve cover in order to ground it?
be as specific as possible

 

Hold it on the the body of the car. The piece in between the headlights. Somewhere around there. You shouldn't ground on the engine.

Why i put it on the valve cover all the time. I see one spark and pull it off.

You should have no trouble using any ground point on the chassis/engine. So long as you aren't using the fuel rail coated in fresh fuel that is.

 

You don't use the engine as a ground because there is probably a good reason why the engine needs to be grounded because it is not a useable ground. You don't ground something to something that needs a ground itself. And he asked for a specific place to ground it so I gave it to him.

You ever study electronics? Its not going to matter, if something is grounded, its a complete circuit. In this case, its not going to matter if its the frame, the engine, the hood, etc..

Hell, if we go by your theroy, then he would HAVE to go straight to the negative terminal. I mean, the frame itself had to be grounded. Thats what the wire off the negative terminal is for.. then you had to ground your engine in three spots so the starter could work, so thats no good either...

 

The frame and body do not need to be grounded. The negative terminal is attched to the body so the body can be used as a ground. Hence everything you ground on the body is grounded to the negative terminal. I'm just trying to say, it's a better idea not to send electrical pulses through you engine.

Well lets see. Your logic just keeps getting better and better. The frame isn't grounded yet the body is? Well, I hate to break it to you, but on a unibody car, the body IS THE FRAME.

 

And for your information every car has a body and a frame. How else can an Integra be built on a Civic frame, but have different bodies??? Unibody means the body is one piece. ie: no seperate sections except for hood and front fenders. Dumbass.

 

what part of the spark plug do you allow to touch the "ground"?

 

Just the tip. Hold the top of the wire so you don't get shocked and place the tip of the plug on the body of the car and have someone crank it quick so you can see if there is spark.

Are you really this stupid? THE BODY IS THE FRAME... If it has a frame then, take your happy retarded *** outside and unbolt the body from it. Take a picture and show me to prove me wrong.

 

I'm not but obviously you are. I went and corrected the mistakes I used in my wording.

Maybe that will help you out. Its good to know you like "just this tip" also.

 

I'm done with this thread. I answered the question that was asked. This thread is not about how the car is built or how electricity works. The question was, "where should I ground my plugs when testing spark?" I gave my input. These threads are for helping people. Not ridiculus arguments.

There is no frame on a Civic. You can't unbolt the entire body and lift it off a frame like old-school Domestics. The body is part of the frame. Once the frame is grounded, so is the body and the entire car.

The engine is grounded. Nothing will happen if you use the valve cover to test for 1 spark coming out of a spark plug. The entire system is grounded. Why do you get shocked when you climb out of your car and touch the hood or roof?

That is true, but you aren't the only one with a right answer. Be more open to suggestion.

And this forum is for helping people by providing CORRECT INFORMATION. The reason you are "done" is because you got shut down. You can clearly see that definition states that the body and frame are one unit. Therefore, it doesn't have a body and a frame. Does that foot taste real good?

Thank you. Perhaps airplan727 can see my point now. But I really doubt it.

 

If you read about Integras. Honda says they used the frame of a Civic to build their new Integra. Just because the frame can't simply be unbolted doesn't mean it wasn't seperate at one point. I'm not saying I'm the only one who is right. Grounding to the engine not the best idea. All of the mechanics I have ever worked with will always tell you to test spark on the body of the car.

I admitt being wrong about the unibody situation, but the Integra was stated by Honda as being built with a Civic frame.

Its based off the same platform yes, but again, there IS NO "FRAME" as you speak..

I am an ASE certified mechanic. In my shop we always ground to the engine. Never one problem.

 

In the shops I've worked at always to the body.
