Spark Plug Testers

[Jeeper]

What kind of spark plug tester do you recommend?

 

[Jbullfrog]

Diesels don't have spark plugs.......

For cars and mowers I have a non-contact tester that shows spark.
Inline spark lights that are great for mowers.
The 40 year old neon timing light for 2-cylinder tractors and mag work.

I would recommend you to have spark plug test light that you can test the wire or distributor or coil to see what problem is. i have two of them and it is very handy for me. i paid 6 dollars each at harbor freight as no problem that it is working good.

Eh... I have a 5$ toolaide inline deal I use. It works fine but they sell these things that are like sparkplugs with a clip on them, so you just put it in the boot like a normal plug and clip it to ground. Works just as well and its kinda cool to watch the spark jump around.

You can also get away with sticking a philips screwdriver into the boot and holding the HANDLE and keeping it about a 16th or so away from a ground point and having somebody crank the engine if you really wanted. I do this alot.

Be careful with that on "newer" cars. Long story short, the electronics don't like those kind of loads. Use a tester like mentioned above. I have many times used a plug with a piece of wire wrapped tightly around the base and the wired to ground on the car. A hillbilly version of the one mentioned above with the test clip.

I have a Blue Point spark tester, it looks like a pen that you press against a plug wire and you can see the spark inside the plastic cover

I also have what looks like a spark plug with a roach clip attached to it

I had a lisle version of that, but I could never see the spark. Wonder what I was doing wrong????

You have to be in a dimly lit room; light is very dim ...

Oh. That would explain it.

Maybe you weren't using the roach clip properly.

Harrumph!

roach clip; roach clip;roach clip.

I know I've heard that term before. Maybe high school in the '70's?

The only good reason to go to the doctors was to steal his Hemos.....

This is what I've used for many years. It's adjustable so you can use it on anything.
