Seen loads of RD and LC generator block connectors melted , my LC last year was on its way out and I've just stripped my hybrid and that's the same, I would never have noticed until it was too late but luckily I was taking the engine out when I spotted it. What's the common reason for this ?
Seriously tho, I haven't had an issue with mine. Bought a load of random Spares years ago and there was a couple in there that weren't melted either and wasn't aware there was an issue. Will keep an eye on this post to find out more.
