    A friend bought a boat with this auto tab controller. All six red lights just blink in unison all the time. Pushing buttons changes nothing. It also has the manual black buttons. They work fine.

    Any thoughts on what to check for, and is there a way to get a manual somewhere?[​IMG][​IMG]

    Per the manual:

    3. All LEDs on the ATC Keypad flash simultaneously.
    Control Unit signal is interrupted. Check Keypad cable for breaks and check firmness of connection into ATC Control Unit.

    That's an old AC2000 and an old RT type manual switch.

    I have the manuals I can email you, you can contact me at
