Why are my wires melting together?

처리 내용

If you are not familiar with the electrical system I would get a referal to a good shop familiar with BMW's. They may have seen it before or at least recognize what caused it. This a case where it must be determined if your melted wires were the cause or the result of another problem. Just installing another harness may result in the same melted wires. The wires melted due to excessive current draw. Normally this should not happen because the fuse should open to protect the wires. It is possible that the wrong size fuse was installed allowing the wires to overheat.
