Fun with alternators ...

    Having been confined to barracks[1] with the galloping lurgi, I got
    bored in the afternoon.

    Luckily, I discovered a long lost tuit, and set off for the garage
    with an alternator in my hand.

    As it had been on the old Optimate since we returned from France, I
    started the old beast up. Voltage across the terminal? 11.96v, and
    falling. Rev it a bit - no change.

    Step one,; remove battery - having established that it's an AGM
    type.[2]

    Step two: remove old alternator. Simle enough. IT does make some very
    odd rattling noises when shaken - most un-alternator-like.

    Step three: Unpack new alternator - it's bigger than the orignial. I
    duly snip and tuck away the green wire from the old capacitor, as
    instructed, and set about fitting the Compufire.

    In summary - it's like re-installing a baby. You *know* it fits, but
    there's no obvious way to get it in there without breaking something.

    After over an hour of inserting, wiggling, twisting, and swearing,
    it's in.

    Of course, when I go to refit the first bolt, it slips out of my cold
    fingers, and drops down the gap between the recently located
    alternator, and the clutch housing.

    Can I find my magnet onna stick? Can I arseholes.

    In despair, I splosh off into town to retrieve madam. The new
    Michelins are a revelation, compared to the old, sown, square ones,
    complete with 2" wood screw.

    Oh well, once the bolt's been retrieved, I've only got to connect all
    the conneectors, refit the battery (with *two* 50A fuses, no less),
    and fire it up.

    Please don't let the bolt retrieval process be an "alternator out"
    job.

    [1] ObMil - I see Kinloss is for the chop, along with the Nimrod
    fleet. They only flew the MRA4 for the first time this year, 13 years
    after taking away the airframe. Luckily, we're also due to have two
    new carriers - but no planes to put on them.



    Sums it up nicely.

    [2] Ordinary ones will boil when confronted with a Compufire
    alternator, apparently.

    Military aircraft are just relics left from the cold war. Nukes are
    where it's really happening.

    Steve, check out youtube for FPV flying. I'm definitely going to have to
    order a system to stuff in a heli.

    Here you go, right "up your street"

    The best part about it: Lee Morgan's Sidewinder soundtrack.

    Yeah, but with just a sim, you can't check to see if the local dogging site
    is active. I was just wondering how long it'll be "allowed" (FPV flying with
    models) before someone gets the idea it could be used for something sinister
    and tries to get it outlawed.

    Isn't it just?

    A pal of mine in Sweden has just got a set up, which is how I learned of its
    existence but I saw last night that you can also get a "head tracker" where
    the camera follows your head movements. 350 degrees of rotation should be
    enough :)

    I'm currently researching types, costs and availability. I can see a set up
    sitting in either a T-rex 450 electric heli, or a Robbe Futura 90 powered
    with an auto stabilising system (if I can get around the vibrations of a Glo
    engined heli). The other alternative is a 4 rotor system like the GAUI 330X
    which looks very promising.

    Didn't we do this a while back with some police force or another's new toy?

    I think it was agreed that it already is illegal if you're doing it for
    surveillance.

    Very probably, ut if so, it'd have been about cops not irresponsible loony
    toons.
    I think it might be illegal to fly down the road and through tunnels before
    heading back home, but I'd do it just for fun. Some **** may decide to do it
    with a plane filled with "a substance".

    Actually, another use could be as a drugs mule. Not much chance of getting a
    shit load on board, but one could drop off a hit for a pal:)

    I think there's a weight limit, but that's about it.
    Heh. Dial a spliff

    It wasn't, thanks to the timely re-appearance of the magnet on a
    stick.

    All bolted in, I then needed to reconnect the battery wire, which no
    longer connects to an easily accessible terminal on the side, but a
    completely inaccessible one on the end. Tank and airbox breathers
    re-routed, it did up "eventually".

    Now, where's the ignition wire gone? Ah, it's hiding behind the
    alternator. Hmm. It was finally coaxed from its hdiing place by a
    hooked length of garden wire, and connected easily enough.

    Both fuses installed, with spacers, battery refitted. Simple enough.

    Passenger footboard refitted, alarm disarmed, key in, choke, button
    "Vrooom". <happy Dodger>

    No more rattles and squeaks from down by my left knee, and it shows
    14.2v across the battery *at idle* (700rpm), and flickers upwards
    slightly when revved.

    Refit three fairing panels and the seat, and it's a go-er once more.

    All in all, a successful afternoon off so far.
