    No.71 Mk.1 Sighting Telescope question

    in Tracked vehicles

    Posted

    Mike I think that the data summary, technical description, mods & inspection standards would be covered in EMER INSTRUMENTS.

    My earliest EMER INSTRUMENTS index is 1972 so it doesn't go back far enough, but Telescope, sighting No.73 is in section S 730-739. So I expect No.71 would be close to that section.

    I think that the REME Museum is one of the few places that might hold such an EMER.

    It is interesting that so many of these did end up as breakdown trucks. Ironic that the Humber Breakdown FV1606 never made it to the drawing board. I have the WO design requirements but it never seemed to get as far as an FVRDE Spec, unless anyone knows different? Wally have you anything further on this I wonder?

    Like most people I am "under the Moon" about the new charges & my reaction like so many others is not to go.

    The thing is I am in my mid 70s & I don't for how long I will be able to make or at least enjoy 500 mile round trips. So there is a temptation to swallow my pride & go while I am still able.

    But I don't know this year quite what I will be going to, it certainly won't be the W&P events that we used to have. There will be fewer vehicles being brought because of the price rise coupled with the high cost of fuel. Not to mention our European friends & traders who find it too expensive, let alone cope with the hassle of trying to get a ferry & the issues of transporting ex-military items across the UK/EU borders.

    Coupled with all that there may well be fewer traders & those who do decide to go will charge accordingly, so fewer bargains to be had.

    In recent years I have been with a vintage wireless operating group. This was good as we had an area near the stalls & their was some good company. The group has split up, so I shall have to do my own thing. At most shows I like to do some Morse code operating & it draws a bit attention & curiosity. But as pitches get bagged for groups by an advance party, I fear I would only end up in a corner of a field cliking away unnoticed. 

    So may well just give it a miss : (

    I wondered if there was anything in EMER WORKSHOPS. Although it covers preservation, it is concerned mainly about long term storage & preservation of mechanical equipment.

    EMER GENERAL has a large section on timber & its preservation, but little on wood once incorporated into equipment. It talks about varnish stains for "general workshop use where a cheap finish is required and of course no further finish is necessary." Linseed oil is not covered.

    Turning to COSA Section H1(a) Paints, dopes & varnishes. Linseed oil was available as boiled, boiled lead-free & raw. The section specific to wooden furniture covers a range of stains & lacquers.

    With no definitive guidance, I would think that if you can see no evidence of deliberate staining or lacquer then linseed oil might be the best way to go.

    Incidentally I have acquired another VAOS Section J1. Although no VAOS vocabulary reference numbers are given the big selection of pictures is rather nice.

    Charging Fault on FFR Series 3 109

    I do get slightly more volts at the battery 25.2 vs 24.9 when the engine is running. 

    Do you mean the static battery voltage is 24.9 but with the engine running it rises to to 25.2?

    With the everything running & charging properly it should be more like 28v. But maybe with this charging fault the batteries are rather drained & not yet had a chance to absorb a full charge?

    Incidentally it is always worth checking the individual voltage of each battery. If they don't match then try to bring them up to scratch & charge each battery separately in turn with a 12v charger.

    Even so the overall battery voltage is not matching the voltage from the alternator output & this imbalance of course is what makes the charge warning light glow.

    I don't know whether you have a Gen Panel No.9 Mk 3   & have twin ammeters or the Gen Panel No.9 Mk 4 with a single ammeter just for the radio batteries.

    If you have twin ammeters it is very handy to monitor the charge current to the vehicle batteries. If you have a single ammeter & without rigging up a voltmeter, you have to rely on the charge warning light extinguishing or at least dim as you rev the engine. Of course it will not extinguish unless the batteries are fully charged. Or you could switch on the headlights & see them brighten as you rev.

    It is important to remember that the alternator output is not negative earth. Negative is isolated it only becomes earthed at the generator panel Mk 3 or if you have the panel Mk 4 it is earthed to the shunt box case.

    So it it is very important that you have a clean tight earth connection on the Mk 3 panel or in the case of a Mk 4 panel that the shunt box is properly earthed.

    Earth strap problems are so easy to miss as people tend to start thinking of darker diagnostic faults & sadly pull apart wires & components that have no faults.

    Good luck you seem to be making progress & taking the trouble to follow the guidance. I regularly get emails from people who say I can't read all that stuff, my FFR Landy (of whatever type that might be?) isn't charging, what do you think it might be : (

     

    Charging Fault on FFR Series 3 109

    I'm a bit rusty as I wrote this some years ago. But most installations have the brown/yellow that goes to a connector to connect to a yellow Unipren wire that travels into the shunt box. It makes no connection with anything in there but merely travels out through another port to socket E of gen panel. I can't remember how far along the line the connector is that facilitates the brown/yellow change to yellow.

    Test one takes me to test 1(d)  and I am stuck here. The test says to check for an open circuit between the double connector at rear of instrument panel( white lead) but I cannot see the double connector. Am I right in interpreting this test as it is a test of continuity from the white wire feeding the charging light to socket E on connector 2 ?

    I took a picture of the wiring at the back of the instrument panel and the wired wrapped in black tape is a concern.

    Yes you are correct. The white lead passes to the charge warning light then to another white lead then it meets a connection to then change to a brown/yellow lead to socket E.

    Don't worry about the 6 white wires going to the black tape, they all meet in a fixed "cinch" connector. I can't remember where it is fixed but the important thing is that the connections inside are good & well insulated from the chassis as this white feed system is not fused.

    Basic principles would not have changed much this is a fairly common guide.

    WO Code No. 9459 Concealment in the Field. Nov. 1957

    It was such a useful guide that it was reprinted, so the market is flooded with repros. The same info but not the same experience as reading the real document.
