I wondered where you were Wally but with your opening shot you are spot on! Well done! Just have to work out how it is used now :-D

More than just mere pallets Tony & there is only the one needed.

Just the one Andy. Once this has achieved the objective there would be no need for another.

Good thoughts Richard but not the right ones.

Dunno Lauren but it wouldn't look much like this wooden thing

There should be some iron fixed to the base of this structure if that helps.

A good guess Richard, but no. I think the one vehicle is Canadian & the other quite different one is American. Look for the dotted lines :-D

A good thought Richard. Yes best get back to the purpose of this thing as the animal name may not help directly. Its neither of those, but follow the dotted lines for a clue.

If it helps I believe there are at least two quite different vehicles that share this animals name. Although getting the animal's name will not give an immediate conclusion to the purpose of this contraption.

Probably Bernard, not a badger.

Yes I was afraid you might be Andy, but you are the warmest so far

Sorry nothing lavatorial this time Tony

Not mine clearance.

Saw one of these at W&P together with a smaller container for oil. Apparently for a Vickers Machine Gun.

It's not one of those (whatever it is) Sniffing around for a clue I suppose? :-D Well here is one then, the creature in question is resident in the UK.

Not a Stalwart Bernard.It is actually an animal & its behaviour would give a clue. But googling this animal didn't match up with this contraption I'm afraid

If it helps, this contraption was given the same name as a military vehicle. The name probably describes the role of this better than it does for the military vehicle. In case any one wonders, it is not called Humber 1 Ton

Lee I can see the line of thought with the era & your BAT experiences. But it is not for that. Surprisingly despite its substantial construction not a great deal of force is applied to it & incidentally only one soldier would need to use at a time.

I beg your pardon :-D Ah I see what you mean. Another good suggestion but its not that. If it helps this is 1961 & it would only be necessary for this particular unit to have one of these.

Another good idea Richard but its not for that.

Looks as if it might be Lee, its a sturdy sort of thing but has a different purpose.

What's this all about?

Ron I think you will find its not an electrolytic capacitor & is not polarised. As far as the capacitor is concerned it is not interested whether the initial energising voltage is 6, 12 or 24 volts. It is not dependant on the earth polarity & has no memory effect of any previous charge, so does not need to be changed per se. It should be rated at 500v to absorb the back emf induced in the primary as the magnetic field collapses as the points open. The effect of the capacitor is to cause a more abrupt switch off & consequently a greater HT output. This occurs at the rate of 5kV per ten thousandths of a second. The capacitors Mike has were in excellent condition when I tested them on a Megger.

Mike the next diagnostic suggestion for the electrics would be to temporarily mount two panel lights in the cab. Each earthed on one side, then one light to the SW terminal of the coil & the other to the CB terminal. Under normal running the SW bulb will be illuminated. The CB bulb will probably glow dimly as the points rapidly open & close. Get used to how the bulbs look when you are running normally. When it starts to go peculiar see what the bulbs are doing. SW bulb should be on constantly. Dimming or extinguishing shows a supply lead or ignition switch problem. There will be parallel behaviour for the CB bulb. CB bulb should flicker/dim. If it brightens up & stays on the points are not closing or the coil CB to distributor lead is failing. If it does not light up (& the SW bulb is still bright) then the points are stuck closed or the lead inside is shorting. That will give you an immediate idea of the behaviour of the LT circuit when it has a failure/ funny turn.

As Richard says. This is from a Lucas training course:
