These were taken out the bottom of some derelict concrete columns , the doors were missing for what looked liked 30 years plus, one was so badly corroded the outer case has disappeared. Now, who would wager these would work still?

I'd say they still worked but I wouldn't wanna be the one testing them lol

Fire them up! That's what fuses are for dan!!!

You`ll need the tap diagram first, unless your playing ballast roulette???

just copied what terminals the old cables were connected to, think i have a good clean one of these somwhere, ones a lot better as seen on the photos, that one works too.

Love this
