Electrical Problem with my 99 SC-1

    I've had a 1999 SC-1 Standard for about seven months. Recently I started
    having a weird thing happen -
    It doesn't happen all the time but is increasingly more frequent.
    When I press on the brake, it seems to disrupt the entire electrical system.
    The interior and exterior lights blink, the ABS, Low Fuel and Brake lights
    come on and all the needles drop to zero (Speedometer, RPM, Gas). This only
    lasts for a second, then everything goes back to normal. Usually. Sometimes
    the ABS and brake lights stay on until I turn the car off and restart it.
    Then it will be fine until I need to press firmly on the brake again. If I
    make the car slow extremely gradually, that doesn't usually happen although
    the car seems to experience a more minor, momentary power drain.
    I would really appreciate any ideas or suggestions. I've taken it for a
    diagnostic once and they didn't find anything.

    You've got a ground connection that's going bad. Check battery terminals
    first, then connection at metal frame point(s) ...

    Also consider your alternator is failing and your battery might be bad
    as well. When you brake your idle drops and the load on the alt jumps

    I know a person who had a similar problem.

    The problem was an electric wire under the floor (driver's side). The cable
    was affected by the calcium and water.

    I hope it can help.
