This could be fixed if you can do it carefully....I've done it before

jace the Coil lead wires broke all the way off to the Core...the only way possible i see it happening is if i could disassemble the Core...which seems impossible since its Welded.

well it is possible to fix...but a bit risky...I done it before by unwounding the the coil a little bit...and till I reached where it broke...I added new coil by connecting it with electrical tape (to prevent from touching the iron part and the other coils...so there is no short) then rewound them using Elmer's glue...(the cheapest most hill billy way instead of using varnish)...but there is NO guarantee of any of this or even guarantee of safety...so...it may not be worth it!

I actually am working on a Crouse Hinds reactor HPS ballast...trying to UNSHORT it.....so far no luck..but I may have unshorted it a bit...but not enough for the starter to sense there is no short to strike!

I also think you might be able to fix up your ballast Devonte, you could do what Jace said about unwinding the coil a little bit and then solder on a new length of wire on to the free lead after scraping the varnish off the wire so it conducts. After soldering the wire on you would insulate the joint with a short piece of heat shrink or liquid electrical tape.

This might not work if the wire broke all the way back to where the coil meets the core though. Also if you do decide to fix it I would be more careful and use a fuse the first time you fire it up.

We'll see.....i dont think its worth it though unfortunately.

Lets put it this way....if you WANT to become a future lighting inventor, or an engineering or even a creator of stuff, electrical guy...or whatever....then it IS worth it to improve skills and learn, and discover! However caution while working on stuff....and know the dangers, and do those and test in safe places too...and in a distance if needed....

also,elmers glue doesnt seem like a good bet especially seeing how hot this ballast gets when it runs.

Actually you would be surprised.....a few people has suggested dipping the ballast in a heated Elmer glue....they do the trick....Elmers glue isn't flammable either...just a good alternative for light testing and collection, but not best solution....just a cheaper solution....It's probably even better than using PAINT which Michael did in the OV-10....although the original red varnish did look like paint!

What about this stuff, my local electronics store sells them in the small bottles.

Yep that is the correct stuff here......but I never could find one LOL....

that varnish looks much better than elmers glue.

Right varnish, you will just need a bigger bottle of it. I still have a transformer I made as an apprentice, somewhere. Covered in red varnish.

you "made" a transformer?...can we see it.

I had premade laminations, but had to make the former and wind the primary and secondary windings myself. Had to make the clamp as well. looks like a regular item, aside from the leadout wires.
