Your cart is empty.Provides an Easy Way to Check Ignition Systems with Coil-On Plugs. Applications Include Ford, Chrysler, Mitsubishi, Nissan and More. An inductive test cannot be performed, because there are no plug wires. The round knob provides easy gap adjustment and the 12" ground wire comes with a shielded clip.

Needed this for a project truck. I had spark and fuel but it just wouldn’t run. This handy little gem found my issue. The coil was weak. Truck runs and drives now.

Hooked up to the end of a plug wire, connected the ground, and discovered I was losing spark to two misfiring cylinders after unloading the parts cannon at everything else. Quick and easy testing with this. Would buy again.

Proved that coil was weak. Compared to other chain saw, I could increase the gap a sizable amount. Something like 3/8 - 1/2" but when I used on suspect saw I could not get past 1/8". I wouldn't call it a well crafted tool thought. Part that threads in has a lot of play. Think you could buy a cheaper one and get the same thing.

Like so many have pointed out. The screw in piece fits so sloppily that the tip can wiggle 1/8 " side to side. Why does the manufacturer continue to make it with such poor tolerance? I assumed the other reviewers just got an old batch. Nope, apparently they intend it to be sloppy and continue to make it that way. Really poor quality!

Instructions pretty sparse.After figuring out I needed to know the secondary resistance of my coil, it was easy to set the resistance on the device.Worked well, showed nice strong spark, paid for itself immediately knowing I didn't need to replace the coil.
