As we don't seem to get Dad's Army in Wales on Saturday night, I got bored so here is a mystery object that caught my eye. This is very much a diagram & is not terribly accurate but this is how it appears in the manual, minus of course the labels. The diagram is only a partial view of a larger thing. But the particular relevance is the presence of items A-D.

Actually now I have thought about it a bit more, what I suggested is not a very good idea because the output negative rail is shared & then there is the issue that the "upper" battery has a negative that is 12v+ above earth. Yes the regulator is internal. I used to have a 12v vehicle that I needed a 24v supply for radios. I connected the radios to an additional 12v battery with its negative going to the positive of the vehicle battery. To charge the upper battery I used a 12v inverter that gave a completely isolated supply so there were no earth clashes. The AESP Technical Description that I have should cover that alternator is an early edition, unfortunately that particular chapter is marked as "not yet published".

Sjoerd I believe this alternator uses the Prestolite regulator 600-9. There seems to be no setting that you can change on this to adjust the output. However if you look at the circuit diagram below you will see it has a diode trio for the vehicle batteries & another diode trio for the radio batteries. It seems that you might be able to use one output that could be regulated down to the chosen charging voltage for one of your batteries & do the same again for the other battery. Is your 110 exclusively 24v? Or is the automotive side 12v & the radio batteries 24v? I don't know how the outputs are configured in the military version of this alternator whether there are two independent outputs or whether they are combined in parallel. But it might be possible to tease out two independent outputs? http://www.prestolite.com/productinfo/alternators/1278680/1278680_wiring.jpg

Or even less, as the odometer is probably calibrated in km

Wales, but how can I change this on the poll? When I voted originally I was in England.

That's good to hear Cori. Looking forward to it, worth the round trip of 401 miles.

Interesting little pamphlets with much sound advice still applicable today, including the warning about cyclists who are "liable suddenly to cut into your path". Vehicle tyre pressures in February 1923 (left) get quite amended in September (right).

Tony for starters: What are the state of the plugs? When were they last renewed or cleaned & how? Does the coil get too hot to touch or at least feel hottish? After 20-30 minutes Does the tip of the rotor arm show loss of metal or does it have deposits? Is the coil designed for the polarity of your vehicle? Or are the primary connections in a reversed bodge (sorry improvisation)?

Yes VAOS Section LV7/HL/HR/KR/CM - Hillman, Humber, Karrier, Commer (but not Humber 1 Ton or Commer 1 Ton)

For Sale: Helmet & visor £20 could take to Newbury Sortout this Sunday or collect from Wales.

VAOS Section LV6/MT1 is not necessarily vehicle specific it covers General MT Stores, Miscellaneous Items. In Sections LV6/MT1 to LV6/MT15 the manufacturer's code TE is allocated to H.Terry & Sons Ltd. What range of vehicles this particular item was fitted to I'm afraid I have no idea without working through the ISPLs of the time.

Mick might be worth getting a copy of the record card by entering the registration in this form: http://www.rlcarchive.org/VehicleSrch On the record card the 2-digit alpa-numeric paint code would indicate the colour & finish.

Laurence just a thought are your brake shoe adjusters all ok? The mechanism is the same for Pigs & there were problems with both the phosphor bronze & steel types due to fracturing of the sleeve wall on the adjuster inner wheel or seizing on apply the brakes. There were a couple of urgent (blue) EMERs issued in 1982-3 about this, I don't know if there was an issue flagged up on Ferrets as well.

Yes it is often the way when there are people plugging away working through all possibilities & someone fresh to the problem spots a missed clue & moves in with the final part of the jigsaw. Anyway well done for picking up on the clues.

First of all apologies to everyone for the gaps & delays. I have no broadband here, our phone supplier is unable to get a signal to us this far from the exchange. Although we can't get a mobile signal, I can get a whisp of one from a yagi antenna on the roof. It is often quite good, but tonight there is a lot of rain & the signal intermittent. Even the speed test site takes 3 minutes to load its start page then gives up on the test! Yes well done! It is built into a sand bag to disguise it as an observation port in a sandbag wall. Picture to follow

Well Wild Card suggestions often get close to the answer Lauren. The hessian is what it is, if you see what I mean.

Nope Richard that might look a bit unusual. Think about the types of materiel I mentioned.

Nope but good guess Richard it is something common & would not be noticed.

Yes I imagine you would Tony

They could fit in Billy but not a transportable thing really.

Not that Tony

Quite Richard, but they don't get in it as such, it just a component piece constructed in a special way.

Not specifically Alec

Yes Lauren well done it forms part of that. So 50% there but what is this particular component constructed in?
