I am retired from the automotive business with 40+ years of experience starting from a technician up to an instructor with a Domestic OEM
To many technicians have been sold test probe kits that are either too expensive or the wrong sizes, or not clearly marked.
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.
