Ever seen this tool?
It’s a pro-chek hi voltage ignition analyzer.
I bought it in the late 1970’s.
This tool is NONINTRUSIVE.
Just put the supplied headphones on!
I use it frequently for spark plug wires
It detects improper firing.., coil output
Especially regarding 5/7 crossfire on a Chevy.
It is a very simple tool.
Have you seen it before?
If so, where?
I need a new one
