    Expecting that you have actually wired the system as required for it to work - you could try the following:

    1. Disconnect the BTS7960 and place in bin.
    2. Order a Sabertooth 2 x 32.
    3. Wiring the Sabertooth in as per the FAQ.
    4. Smile as everything works as it should.
    5. Cancel the appointment with the hair transplant surgeon and throw away the box of Valium.
    6. Send Seattime a PM thanking him for being such a great man.
    All TIC of course :D, but with a lot of truth behind it.
