    Unless, of course, it's self-superiority _by_ Americans.

    Yup. I don't have a problem with my inability since British or English is
    not my first language, fortunately I have a spellchecker that can help me
    out with most things...

    Not quite. Since 'bastardised forms' is a plural none, the correct
    reference would be "There are" or "There're". You used "There's" which is a
    contraction of "There is", which is meant for use with singular objects, not
    plural ones.

    Even 'American's can spot that error in your English.

    That'd be [sic], then.
     
  9. Talk to most Americans and they won't hear you. After September
    11 2001, they didn't hear a word of the responses to the query
    "Why do they hate us so?"

    Is this from a limey newspaper?

    I am curious about two things.
    a) Yorkshire is part of England- what language is spoken there?
    b)What has all this to do with electrical engineering?

    As a Canadian, eh, I can cope with both US and British English. I don't
    pretend to understand Yorkshire, Newfoundland, or Ozark dialects.

    I've no idea, it's a curious blend of languages...

    You know what I hated about the movie "An American Werewolf in London"?
    Trying to understand the bloody accents of the chaps in the little bar room.
    I suppose that was english, I mean it WAS in England and all, so what else
    could it had been?

    | Let me expand this discussion slightly. If the "fresh" battery is
    | connected to a charger
    | such as a car alternator, then leaving it for a few minutes to get some
    | charge into it
    | is a great idea.
    |
    | However, if it is just a fully charged battery it cannot under any
    | circumstances charge
    | the dead battery. You need at least 12.9 volts to get the battery
    | chemistry flowing in
    | the right direction, but the voltage of even a fully charged battery
    | will not be this high.

    I disagree. I have accompished charging one battery that was drained
    by paralleling it with another battery of like construction. But for
    the most part, what you say is valid. The drained battery was not
    overdrained to where it might be damaged, and it didn't get anywhere
    near a half charge from the connection. But it did charge enough to
    see some voltage from it again. Of course, the ideal is to have enough
    voltage to keep charging current flowing up to full charge. But to say
    such charging simply cannot even get started from battery to battery is
    just not consistent with my experience.

  19. We were somewhere around Barstow, on the edge of the desert, when the
    drugs began to take hold. I remember "computar2006"
    Your battery was on its last legs anyway. No way could jumpstarting
    knacker your battery.

    Some use 42v now, notably 7-series BMWs, and - of course - most trucks are
    24v
