Not really efi ..........

[Simon Quested]

Hi all

Nothing to do with efi .....but I had to share this with you all.

This story was related by Pat Routledge of Winnepeg, Ontario about a repair
call he handled while living in England.  It's common practice in England
to ring a telephone by signaling extra voltage across one side of the two
wire circuit and ground (earth in England).  When the subscriber answers
the phone, it switches to the two wire circuit for the conversation. his
method allows two parties on the same line to be signaled without
disturbing each other.  Anyway, an elderly lady with several pets called to
say that her telephone often failed to ring when her friends called; and
that on the few occasions when it did ring her dog always barked first.
Pat proceeded to the scene, curious to see this psychic dog.  He climbed a
nearby telephone pole, hooked in his test set, and dialled the subscriber's
house.  The phone didn't ring.  He tried again.  The dog barked loudly,
followed by a ringing telephone.  Climbing down from the pole, Pat found:

a. The telephone system's ground was disconnected from the ground post and
used to restrain the dog via an iron chain and collar.
b. The dog was receiving 90 volts of signaling current.
c. After several such jolts, the dog would start barking and urinating on
the ground. 
d. The wet ground now completed the circuit and the phone would ring.


Unfortunate but very funny =-)

Cheers

Some people can tell what time it is by looking at the sun. 
But I have never been able to make out the numbers.
