Handy little diagnostic tool
👍 Pros: Works fast for testing HT supply to a spark plug. Sturdy and simple — no settings to fiddle with. Great for DIYers doing engine diagnostics. 👎 Cons: Only shows presence of spark, not strength or timing. The short lead length might mean you need to lean over the engine more than with longer cables.

Saved Me Over £100
Not normally a great fan of Sealy, but I have to say the quality of this does feel very good, plugged into my strimmer because I was pretty sure I needed a coil pack, but I’m glad to say it’s working fine and tests alright confirmed by this tester. Overall very impressed with this full stars from me

Easy to use most of the time
A good little gadget, it worked well on my old 1970 mini, but wouldn’t fit my Alfa as the plugs have an extender & it didn’t fit onto that

If you use a spark plug without a screw cap not for you
When advertised it noted for use with motorcycles but will not couple with spark plug main leads

Sealer inline HT tester
Arrived on time with easy instructions to use the inline HT tester, It's indication is shown by a bulb being lit when connected in series with the HT cable for the car ,it can be used for motorbikes lawnmowers etc. to indicate a good HT just be aware when in use the HT is high voltage and be safe. A good piece of kit when checking for a fault if there is misfiring or unable to start the vehicle etc.
