About Me

My Background

I am retired from the automotive business with 40+ years of experience starting from a technician up to an instructor with a Domestic OEM


Why I Started This Business

To many technicians have been sold test probe kits that are either too expensive or the wrong sizes, or not clearly marked. 


Terminal Size Matters

What the Hell is Large, Medium, & Small!
Now that GM has terminals that are 0.40mm & Ford has 0.50mm. You need the correct size to prevent damage.


My Test Probe Kits are MADE IN USA with Domestic & Imported OEM Terminals.
