    Hi Lee

    Clive is correct , when a fuse blows the diode will only conduct
    while the motor is generating a higher voltage than the power supplies output

    just because its what I have in my spares box I would use
    a 1N5408 - 1000V PIV 3A diode
    ( I think I used them to rectify the 250V mains )

    with a 70 to 80V DC power supply a 1N5401 - PIV 100V 3A diode would be OK
