    I found an old Gateway Profile 4 AC adapter at a garage sale.
    It's rated 12V at 13.3 amps, so I figured I could run my Yaesu
    with it.
    When I cut off the original plug, the outer wire (shield like) was negative
    and the center was positive, which is fine.
    But, in the middle of the positive wiring was another smaller red wire.
    Also, it seems like the positive wire and little red wire are connected (shorted) at the plug.
    Is this little red wire some kind of voltage regulation sensor and should it be twisted
    with the positive lead when I hook it to my radio leads?
    Without it hooked up, the voltage from positive to negative is 14.4 volts.
    With it, it's 12v
    Thanks for any input. --Mick

    Yes, it acts like remote sensing. Connect it to the positive lead.
