    not going to be able to help despite your dad going through it all with me, red with black strip does not even ring a bell!

    looking at a diagram online it seems that the wire goes to the servo motor

    If it is a TZR250 loom (Road or Racing) 1KT there should be no Red/Black.
    There is a Black/Red which runs from the Control unit to the Servo motor along with Yell/Blue, Whi/Red, Whi/Black and Black/Blue.

    The Whi/Red is a single connector the others in a four way.

    The CDI has Whi/Red, Whi/Grn (Grn/Red and Whi on racing harness) to the pick-up.
    Brown,Green,Red to the Magneto.
    Blk/Yell to the control unit.
    Blk/Whi to engine stop (ground to kill).
    Blk to earth.
    Orange to coil.

    Not sure if it is of any use, but I have an original 2ma colour wiring diagram (held together with a bit of duct tape in true hover style) that I'll gladly drop round. It's part of the yamaha service info book (not the workshop manual) and is dated 1987. Likewise it doesn't show a red wire with black trace, only a black with red trace.
    PM me if you want to borrow it.

    According to the wiring diagrams I've got there is also a black/red between the oil level gauge and the oil indicator light. Unlikely to be required for a hovercraft set-up.
