Koiltester info needed

[sanford51]

I have a friend who has an automotive coil tester made by Koiltester. I attached some photos. Anyone have any idea where a manual or electrical diagram might be found?

Thanks,

Sanford

I should have called it a Koilster, not Koiltester.

That's way cool! Never seen one before.

HAMB forums and groups have a lot of info on these and other similar vintage gear.
