Wire resistance with age, + M&H fuse box

    One question for an electrical engineer type out there: does the copper wire conductor itself actually build up resistance over time (e.g., 32 years), or does all of the age-related resistance come from the terminals and connections? That dim tail-light syndrome is really a drag....
    It really doesn't seem possible that the conductor would actually gain resistance unless it's physically compromised (broken strands, etc.).

    Also, has anybody ever gotten a reproduction dash harness from M&H? If so, how about posting a picture of the fuse box?
    Thanks! :beer

    It's usually where the wires get crimped onto the connectors. Heat builds up at these connection points causing them to short out. The wire itself doesn't have any problems, unless there is moisture present,then the wire will start to corrode and that will lead to shorts as well.

    Typically, the wire itself may age, adding slightly to the resistance, but other connections, such as switches, grounds, and fuse CONNECTIONS will age faster. I would be looking at places of interface, such as connectors, switch contacts, and grounds as potential culprits before condemning the wire itself.

    That's kinda' the answer I was looking for. Thanks, guys.... :beer
