    It ran perfect last week. But last night it wouldn't idle and I don't think the charging system was working. It would come and go. When the lights would brighten up it would idle too. But it wouldn't stay that way. I can't visually find a loose connection. Just above idle rpm it sounds like its skipping.

    Any ideas?

    Could the voltage regulator cause this?

    Terry I have a 40 merc 1995 model and the only time I see any change
    in my lights is when I am starting my boat. It looks to me that if you have
    a good hot battery you would have to have a large draw of current to
    dim the lights (cranking the motor or a short coming and going). or possible
    bad connection.
