Fabrication of Spark plug testing machine

This is a simple mechanical engineering project which can be executed at low cost.

Construction

A Spark plug tester essentially consists of a metallic portion followed by something that looks almost similar to a Spark Plug and a connecting port in a tubular arrangement.

What does the tester do?

The Spark plug tester performs the following functions to check the proper working of the Spark plug.

1. Checks if the Spark plug is accepting current from the wires that go to the spark plug.

2. Proper firing of the Spark plug

The main idea of using a spark plug tester is to avoid the removal of the spark plug and testing it. This leads to saving valuable time.

How does it perform the above functions?

a)     Testing the wires:

At first, disconnect the wires from the spark plug which you wish to test. Place the wire to the end of the tester. The tester is then clamped to the engine block. This grounds the unit and allows the flow of charge through it. With that done, you should fire up the engine and keep an eye on the end of the spark plug tester for sparks. If sparks are visible, then the wires are working fine.

b)    Testing the Spark plug firing:

The long end of the spark plug tester is inserted onto the spark plug. The other end of the spark plug tester is plugged into the boot on the spark plug wire. Fire up the engine and look for spark in the window of the tester.

Note:

Testing the spark plug is simple but you should make sure it is done the right way so as to not hurt yourself in the process.

found your site on del.icio.us today and really liked it.. i bookmarked it and will be back to check it out some more later

last week our group held a similar discussion on this topic and you illustrate something we haven’t covered yet, appreciate that.

Its nice to have spark plug tester,because i have experienced shocks,generated in the process of testing the spark plug when it gets shorted or coated with carbon…i request to send me the details of the spark plug tester…

Thanks for the very useful project ideas. Plz kindly send me full details I need project work very very urgent

Hello.
I would wish to purchase a sparkplug test.
Please give a quote.
For use in Nairobi, Kenya.
Regards.
Mike.

pls, i need the full details for this project urgently as i am supposed to defend my project next week. I will be very grateful if it can be send within the next 3 days to enable me prepare my report. Thanks alot for your help.

Thanks for the very useful project ideas. Plz kindly send me full details I need project work very very urgent

hello sir,
this is very interesting kindly send me all the information for doing this as my major project………

hello sir,
this is very interesting kindly send me all the information for doing this as my major project………
and this site is very very helpfull for the growing engineears.thanks a lot

Hello. A very interesting device this is. Please could you send details of its construction to me. I appreciate your attention in advance.

It is really interesting, mechanical engineering is extremely wide and interesting hence it becomes so complicated as compared to any field of engineering.In addition to this,very soon i am starting my project,so i need some guidence, thank

sir
plz send full details of this project……..as i am doing project in this semester…it will much useful to me

sir,
its a nice project can u provide further details of cost and how to make it through my mail id?

sir,
As i am in my final year of engineering,shortly i am going to start my work towards project,so I will be very much thankful to you if you send me further details of this topic to my e mail id,thank you.

Please, send me the details of this spark plug tester project so that i can try it for my final year project. Very urgent please!!

I’m very much interested in this ,I want the start up details so I can be confident.in doing it , could you mail me the components required and how to start from beginning
