I am looking for a Spark Tester like the one I lost, below is the best description I have:
Shaped like an Over-sized Ball Point pen
The top was made like the terminal at the top of a spark-plug
The other end had a Short wire with a clip on it
There was a hex-head screw that you could adjust the gap
Marks along the side for the voltage of the spark gap to ~100,000 volts
The body was dark-brown or black
It would fit in your shirt pocket with the screw all the way in
Sort of like a mini version of the:
Lisle Ignition Spark Tester
Order No. LIS50850
or
Thexon Ignition Spark Tester with Adjustable Gap
Order No. THE404
Thanks
