    Okay, here's one for you. How can you tell if a vehicle has been switched
    from positive to negative earth?

    My ammeter seems to indicate that I'm not charging and my warning light
    agrees. Checking my voltage regulator gives odd results. So I decided to
    put in an alternator as you've all seen. But when I pulled the instruments
    out to change the leads on the ammeter, I discovered that someone had
    marked a - on the upper lead. This lead had the brown/white wire attached,
    which to my eyes should be on the positive in a stock configuration. There
    are some other wiring changes back there including supplimentary gauges.

    The truck runs well enough with the positive terminal of the battery
    connected to the ground. The warning light and ammeter complain. The
    generator seems to be pumping out power of some sort. It's a IIA 88" petrol
    with positive earth. How do I check?

    Really, I'm not an idiot. I'm just very new to series trucks. C'mon, ask me
    a question about programming the ECU on a Miata...
