You stick a screwdriver/screw/something metal in there, and arc from that to the plug... Very carefully!

You can hose the ignition on new cars quite easily!!

If you have a timing light, use that. If not, leave the plug in the cable, ground the exposed part of the plug against the head and watch for spark across the spark plug gap.



"In science it often happens that scientists say, 'You know that's a really good argument; my position is mistaken,' and then they would actually change their minds and you never hear that old view from them again. They really do it. It doesn't happen as often as it should, because scientists are human and change is sometimes painful. But it happens every day. I cannot recall the last time something like that happened in politics or religion." (1987) -- Carl Sagan

I think Harbor Freight Tools, has a few different tools that aid in the checking of spartk at the plugs. If you have one in your area.

There is a spark testing tool. One end goes into the plug wire, the other gets clipped onto a metal part of the car. Has a variable screw so that you can see how much spark you are getting.

You could dig out that old induction timing light.

mbs and Z- now THAT's what I'm talkin' 'bout! Although my is a little more wedged-shaped, but big and chrome nonetheless.

I've had it for years but it's been a long time since I've needed it, and probably won't ever again.

Safest way is with an induction timing light for yourself /ignition cables/ and ignition system as a whole. Next option is [www.amazon.com] In Line Ignition Spark Tester. As a very last resort, do what john o said. Anything involving removing the ignition cables from the spark plug might damage the cablesif you are testing more then one.

What is the problem, besides no spark? Assuming its an auto. I've run into three different problems with a car not starting. 1. Timing belt/chain was busted. 2. Bad Ignition Control Module(sputtered on an off then died) 3. Bad ingnition coil. As a preventative measure, replace distributer cap and rotor, if it has one. And ignition cables.

That was the model I wish I could have bought. I ended up with the cheaper, plain black model. Still have it (and the dwell/tach) somewhere in a bin in the basement.
