    Car cuts out occasionally

    Let me paint my scenario...I'm pretty sure as to what the problem is, but lets see what the masses think...

    ...every now & again, when I'm driving at a low rate of speed (15-20 mph-ish) and I flick on the high beams (Note: This is at night), power cuts out for a quick second. However, the motor doesn't die, I don't have to restart car myself. All I notice that when this happens is that my radio cuts out, & the battery & ABS light comes on. This happens maybe once or twice a week. However, it happened twice last night.

    I'm guessing that this has to do with either the voltage regulator or alternator. I got my battery & alternator tested at 4 different places and 3 of them told me that everything is at normal operating levels. One place told me that I may have a dead cell in my battery.

    What do you guys think....any suggestions?

    I dunno I'd like to hear what some people think about this also, as I have a similar problem.

        That rather sounds like a poor primary power or ground connection.
        The car makes it possible, but the driver makes it happen.

          Well...checked the power connection last night when we put the car on the lift. Everything looks tight on there. There is a small amount of corrosion found around the wiring on the voltage regulator.

          I do want to add that every time this occurs it resets my OBC & radio settings.

            I am assuming you have cleaned the corrosion
