output voltage of a coil

Does anybody know what the output voltage of a stock 60's - 70's chevy coil would be? I'm just trying to help out a friend
Thanks

If memory serves me correct in say 85 they were hovering around 30K so I would imagine a little less.

Thanks Bam Bam
That's what I was thinking. I have a buddy that's wanting to use one for a powder coating power supply. He's talking about using a 24 volt power supply Thur an rheostat to provide voltage to the coil primary. In turn getting 30,000 to around 50-60,000 volts out of the secondary windings

well you can use a newer coil and get pretty close to that with 12V...

something else that may work is a neon sign transformer they put out those kind of voltages

wait a minute...
you need DC the neon sign transformer will be AC i guess you are better off going with the coil.

I think the neon sign transformer does put out DC (not sure) but it's only 6000 volts. My buddy was needing around 25,000 to 50,000. I was thinking. Rheostat and a 24 volt powder supply would do what he wants.
Thanks

It would have to have AC connected to the coil (transformer). A car uses points or electronic circuits to accomplish this. Straight 12v dc hooked to the primary side of a coil accomplishes nothing but produces heat such as burning the coil up.
