This ballast came off my 32 Ford with a 12 volt conversion.
I believe I burned it up by keeping the ignition switch on all night.
Do you know where I could get another just like it?

Are you sure you've cooked it? I'd think it more likely you've burnt out the coil if ignition has been left on....

I'm with Brian... I don't see a burned out area. Just yucky cruddy. Put an ohm meter across the posts. Somewhere back in the ancient archives, one should find a 'fix' for these things... like, a good cleaning on the ends of the coil, and soldering those joints. I believe acid flux solder was recommended. I know I did this on the resistors for both of my cars, and they both became totally functional.
And.... if your 32 has a 12V conversion, why is this resistor still being in the circuit. I'd suggest thinking this through again.

Probably all us with old cars have cooked a coil. The best prevention I have found is a battery cutoff switch that mounts on one of the battery posts. Turning mine off after using the vehicle is part of my shutdown routine. They are cheap and effective. Now, if I could just find one for my 8 decade brain so I can find the keys!

Looks like an original 0.5 ohm ballast for an original coil. Not high enough for a 12 volt coil. Should be about 1.5 ohms.

I don't think anyone produces a 1.3 to 1.5 Ohm ballast resistor that looks like an old OEM one. Some folks just use a 3-Ohm type coil and bypass the resistor completely for 12-volt conversions. If a 1.5 Ohm coil is used then a ballast is required.

You should be able to determine if you toasted it by using an ohm meter to see if it still has continuity.
