Is there a bench test for my 6 volt coil for my ‘50 Ford v8?

connect 6 volts to negative side of coil and connect a lead to the high tension side of the coil ( a spark plug wire ) run another lead to positive side of the coil and momentarily ground it ( simulating points opening and closing ) high tension should produce a nice spark when you break the connection. Imho.

Coils (and condensers) will often work fine when cold, but then fail when warm from usage. A bench test won't tell you how it will act under real life conditions.

I assume you would do the test "rustedorotted" suggests on-the car. I believe you you should get a healthy spark up to 3/8 inches or so gap.

An old school coil and condenser tester is what you need. My old 1940s era Herbrand tester is just the tool. It even has a Heat setting to re-heat the coil to simulate underhood conditions. I demonstrate it in this short video, and also show the effect of bad condenser on the spark. https://youtu.be/7thA6UA5kbk

ndnchf, was that Herbrand tester made in Fremont Ohio ? There was a "tool maker" company in Fremont that made all kinds of tools, but i'm not sure about electrical items. Thanks !!!! Mike
