ABN Inline Spark Plug Tester and Coil Tester Tool 2-Pack - Straight Boot Inline Ignition Spark Tester for Car, Motorcycle, Lawnmower, and Small Engine

I use them for my bass boat to check the spark plugs and coil packs for my outboard engine on my bass boat. The marina is too expensive, use this tool first before you go to the marina and pay those prices just to change a spark plugs or coil packs.

works good. hard to see in bright light

Worked as advertised.

So much help to me. Although they are cheaply made they did everything I needed know and to find the problem with my riding mower. Thank you.

I just needed a tool to check spark and this did a good job. I am satisfied

I REALLY needed a spark tester for my 2 mowers, and this one fit the bill, just perfectly! Exactly as described, Fast. Ship, A+ Pkg,, and super cheap price!! I thought I ordered one, but it was actually sold as a 2 pack!!! I kept and used mine and sold the other to our local online auction. I actually made money, so I got mine for free!

A must have for fuel injection vehicles cause there's no holding a plug up to metal to check spark on injection ...short enough to get in tight spots and long enough where you can see it from driver seat or hand through the window to get to key switch

These things are a must have for engine diagnostics. The only issue I've ever had was the boot and clip sliding off. After I recrimped the clip back on all is well. Nothing really complex to this at all.

Más o menos. Cable corto y bric ala corriente.
