Hah! Looks pretty good from the outside - should clean up nicely.
I guess the person trying to troubleshoot just had one spool of wire... and used it for everything...
I would start by labeling with masking tape each connected end of the red wire, then testing continuity between the other (still connected) end and seeing if there was in fact a break.
Second thing to look at if there is no continuity is 'should there be continuity here'?
Of course you could do the interesting thing and try to fire it up... but I wouldn't. Not with loose bare wire hanging everywhere and a missing coil stop somewhere.
Nice legs!
Coney Island is a fun player, I think you'll like it once it's going.
