Tonights mystery item

[Graham]

OK TR playmates who can tell me what this is, its the size of an ignition coil but only has a single -ve LT connection and the cable coming out off the base appears to be some sore of drive cable. the fitting on the other end looks almost like an ignition switch but if it is the barrel has been removed but looks like there are 3 terminals on the rear of it.

 

Any clues any body ??

Magneto ?

 

Bob.

Magneto ?

 

Bob.

No don't think so Bob, should have said it was fitted to, although not connected to, a TR5 it was fitted vertically to the same panel the wiper motor sits on the coil bit was in the engine compartment the bottom stuck through into the passenger footwell

Some sort of anti-theft device?

[Dick]

Some vintage ignition coils were fitted with key locks....just like this.

It is probably made by Delco Remy. They were called 'Switch Extension Coils'

 

Do you know what the resistance of the primary side is......it is likely to be 6volt.

 

Some vintage cars did not use the chassis as an earth return which could be the reason for the multiplicity of wires.

 

If you dont want it, I would advertise it, as it could be useful to someone.

 

There is a picture of one in Motor Repair and Overhauling, Vol 4 page 408.

 

Strange it should turn up on a TR5. I guess it was made in the 1920 / 30s.

Could have been fitted to someting interesting, I wonder what.

A safety ignition coil, not possible to short circut under the bonnet.

Friend of mine used one, alway when he had any ignition problems this caused more problems.

Please keep it at your workshop as a souvenier.

It doesn't look like one Roger. I'm building mine as a 2197 issue part-work. I started it in 1976. First issue 99p. I get the last issue next week! 13A plug. The newsagent has organised a streetparty and brass band.

Apparently you can now get one from Ikea.

It will not beat a gloppiter gloppiter machine.

Loved the mystery Graham but had to look up an 'Interocitor' RogerH.

 

'An interocitor is a fictional multi-functional device that first appeared in the 1949 story "The Alien Machine", which became the beginning four chapters of the 1952 novel This Island Earth'

Standard on Volvo Amazons but a pain if the coil gives up, the ignition switch is not easy to remove. Its a Bosch coil so not often a problem.
