I'm repairing a fancy broken microwave that I bought for 20 pounds from someone who wanted to get rid of it

I'm not completely sure if my repair will fix it but I couldn't find any other source of failure. I searched through the entire microwave and found nothing besides a small mark on the capacitor to the magnetron (the heart of the microwave creating the microwaves). When I pried open the lid I saw that the coils had burn marks on them, evidence of electric arching between them and through the lacquer.

So I replaced the capacitor by snipping it off with wire cutters, replaced it with a new one fastening it with screws, tried my best to apply new lacquer on the coils and reassembled the microwave. I am going to try turning it on tomorrow and hopefully it won't burn up and it will start heating food again 😳
