Rotax Evo coil burnt out (see pics)

Hello guys.

New on here, I’m from across the pond in England and just wondering if I could get some answers on my issue.

Bought a rotax evo engine with a good Tonykart chassis, unfortunately when I went to start the kart the coil completely burnt out ? I will attach a photo, the guy I bought it from is baffled by it and will sort it but I’m just curious if anyone has had the same,

The coil still gets voltage but the spark plug gets no spark? Not sure if it will of damaged the ECU or knackered the plug (spark plugs on order)
