Pen-Style Ignition Coil Tester
Rough idle? Start with a coil check.
Check for ignition activity with the coils still installed. Compare the light’s response from coil to coil to see where to look next.
At the coil
Watch the indicator as you check
Bring the frosted sensor tip near the coil housing with the indicator facing you. The light responds when the tester picks up ignition activity.
Coil-to-coil checks
See which response stands out
Hold the sensor tip in a similar position as you move from one coil to the next. If one responds differently, use that observation to guide your next check.
Built-in pocket clip
Keep it handy between checks
Slide the clip over your work-shirt pocket so the tester is easy to grab when you move to the next job.
Back at the workbench
Keep it with your hand tools
When the check is done, store the tester with your sockets and ratchet so it’s ready for the next job.

Frequently asked questions
Do I need to remove the ignition coil?
You can make the initial check with the coil in place when the housing is accessible.
What should I do if one coil responds differently?
Use your vehicle’s diagnostic procedure to confirm the cause of the difference before replacing parts.
Can I use it after a repair?
Yes. Compare the responses again after service as part of your follow-up check.
