There's one of these for sale near me for what maybe a good price. Looks like it covers a good variety of relays but I can't find any info on actually using one or who Cornwell re-branded. Does anyone have experience with one of these?

I've seen that in a couple different brands, mostly just see the guys that have that kit using the adapters with a test light.
I have the Lisle 60610 kit but mostly just use a test light or Power Probe once you know which terminal does what it's about all you need

These are my preference. They control the load side, so simply by seeing which one fits you know which pins are load/control. Switch to control the load, loop for current probe measurement.




Last result, made by cal-van.


This is their newest version, which for some reason was made bulkier?


OEM tools will sell you the original design.





This was a release in 2011. Various brands, including tool trucks, sold it.
