Thanks Bob,

Will look at the thread. Good rainy day activity in Melbourne today.

Cheers!

Jacques,

I have thesame brass switch plates on my dash panel.

Don't remember where I got them from, but it'll come back to me......in time.

They are currently green all over, but I have practiced a technique for filling-in the wording etc with black at a later stage. Will have to look to see if the extra hole has been added. I have a feeling this has occured.

Added 17:15hrs. Yep, ignition hole enlarged. I have installed a keyed ignition switch there, for better security. Not much better, mind!

Another item I picked up at Bendigo last month was a NOS right side ignition lead conduit with an earthing strap for a Ford Sidevalve/Flathead V8.

I assume it was for radio suppression as used on Ford military vehicles based on the number of earth straps used throughout many CMP's. By the length of it I would guess the end goes under a water pump bolt.

Just wondering why it was necessary in the first place as the bolts that hold it to the intake manifold would effectively earth it to the block anyway? Am I missing something about electricity?

Thsi is the second right side conduit I have with the identical earth strap so I assume it was not an ad-hoc modification.

Most if not all the late production Fords I've seen here have bonding all over them, I've always thought it related to radio suppression, but as few were fitted with a radio I don't understand why such a large amount of resources should be allocated to this. The conduit is identical to many I've seen with the soldered on strap. I don't have any idea why this was necessary either.

Keith, as I understand it, radio suppression has two aims. One is to eliminate vehicle interference with on board or nearby equipment (friendly). The other is so as not to alert the enemy to the presence or movement of motorised vehicles by interfering with their equipment. They may even be listening for it.

Thanks David, that makes sense.

On the topic of radio interference or static, I was intrigued to learn that this was exactly what the early Marconi radio signals consisted of. A Tesla coil and antenna was used to broadcast static that was interrupted with a Morse key to send the message. How stunningly simple is that?
