hopefully my new relay sockets come before the weekend so i can rebuild and extend. ill document with pics everything when i pull the harness to rebuild it. i did notice today that it almost seems like the relays themselves are coming apart. i do agree that the heat itsself shouldnt be the issue, but ive verified the +12 and ground connections and they are clean and the ground shows no potential difference, so its either a heat thing or possibily the relay and relay socket contacts just arent making good solid contact, or they just cant handle the current. that would make sense because thats where the melting is occurring, the socket and contact area, all of the wire is fine even right out of the sockets, no signs of overheating/melting anywhere.
like i said, i'm going to try and be as helpful as i can be when i pull it apart and inspect, i want to remedy the issue for myself but also for others because this kind of failure can have catastrophic and extremely expensive consequences. i guess im lucky because i know enough to troubleshoot it at roadside and keep things going, but its a nightmare at this point because im having to mess with them 3-4 times a day to keep from overheating...i literally have blisters from the relay packs being so hot lol
