    For some reason, the brown wire going from the back of the AC socket and to "L" on the power supply came loose, but I don't know where to put it. I don't want to just randomly place it on the possible three pins, so I'd really like to know where. I've looked all over this forum and just didn't find it. Also watched Marquis' video about electronics and while you can see the socket, I can't tell where the wires go.

    Again, this is the brown wire on an R1+. Sorry to be such a novice after all this time, sigh.

    So you KNOW it is the LINE/LIVE (L) input on the box -- what are you missing? The position on the A/C plug?

    There are three prongs on the A/C socket,
    LINE - L (black/brown)
    NEUTRAL - N (white)
    GROUND - GND (green)

    However only two run to the power supply directly IIRC. The plug looks like this:

    Function label Color, common Color, alternative
    Protective ground PG bare, green, or green-yellow green
    Neutral N white grey
    Line, single phase L black or red (2nd hot)
    Line, 3-phase L1 black brown
    Line, 3-phase L2 red orange
    Line, 3-phase L3 blue yellow

    This is what it looked like before I opened this thread. I’ve since moved it to the left prong in this photo directly in front of the black and now have power, albeit the heated bed is runaway, the hot end won’t heat up, and the stepper motors won’t move.

    OK, so what wire is out of place? Those are all landed...
    The brown, black and grey (from your picture) run over to the power supply.
    Brown = LINE (L)
    Black = NEUTRAL (N)
    Grey = GROUND (G) -- often green, but apparently grey in this case

    perhaps I am misunderstanding the question :)

    The brown wire. Since the photo, I moved it in front of the left black wire. I guess you could say Left on C.

    Ah, OK ...
    that sounds like an electronics failure, not an AC failure.
    You were correct to move the brown to the same pole of he fuse as the black.

    It is possible that something has died coincidental with the wire coming loose.

    Argh, so either my new ramps is bad or the Arduino. Sigh...

    Yes... I would start by disconnecting the Arduino and RAMPS and plug into the PC with the Arduino and see if it connects OK.
    Assuming that is the case it is a bad RAMPS -- and that is the usual suspect.

    If the Arduino will not connect (with the RAMPS removed) then it is bad. You need a New Mega 2560 and reload the firmware.
    If it is good then the RAMPS is the culprit.
