Lisle 19380 Spark Tester

Great tool

The tool did not work. I tested it at night with the garage light turned off. With the engine running, I placed the tool on the ignition wires and it did not light up for any of the cylinders. I emailed the company for support and his only response was, "You need to do it darker area."

Well, time for me to add my two cents here.On the one bad review here, so you got a bad one, does not mean there all bad. I see the positive reviews outnumber the one bad one so what does that say. One bad apple, don't dump the cart. The one I received works as stated. How, don't ask me, I don't know, but it does work. There is not much to it so as I see it unless you run over it with a tank or use it for a punch it should last a good long time. The easy way to check spark for years was to grab the wire with one hand and stick a finger of the other hand in cold coffee and see if it heats up. With this little thing them good ol days I guess are gone, and the fun that went with it, cause this is faster than waiting for the coffee to heat up.Going to use it for a spell and then probably buy a few more to give out as gifts to my friends and employees who I am told prefer cold coffee over my idea of how to heat it up.

Could not find this at Napa, AutoZone… nowhere for this old school induction spark plug wire tester. No disconnecting spark plugs and fitting awkward extensions over plugs… just touch to a spark plug or spark wire that’s supposed to be firing… if its good, this will light up with each spark. Super useful tool!

Didn't work and Lisle always has good tools

Big help finding out what was wrong on my 93 Buick LeSabre, found out the cylinder #6 wire was not firing. So i changed the plug and the plug wire still not firing so changed the Ignition Coil and WORKS. Thought for sure it was the fuel injection but the way it was running (chugged) but missed a little bit. The Coil was real easy to change (2 bolts) the # 3 on the coil did fire but #6 on the same coil did not. The other 2 coils (3 total) were good. Very simple to use, dropped a star because I dropped it and the light bulb went out and No replacement that I know off so I need to buy another one.

Saved me a lot of time troubleshooting my Suburban

Flash is only visible in dim light ONLY. The flash is so slight that it is only visible if the any light is almost distinguished. Lisle is a fantastic company and I have used their tools for years and will continue to purchase their tools as needed. This is not a reflection on the company but a reflection on this tool only.
