Re: Restoring Rusty - Ignition Switch Assembly Anatomy

ok so let me share with you the anatomy of the ignition switch assembly

first of all it is mechanical and not electronic, say what? yes the actual ignition switch does have wires plugged into it, but it is operated / manipulated mechanically

so it all starts with you putting the Key in the Ignition Lock Cylinder (as opposed to the door lock cylinder) notice I did not say what we all have heard andy maybe even said "Put the key in the ignition" umm no or worse "Put the key in the ignition switch"

On our trucks the key goes into a Lock Cylinder and there are no wires (at least on mine) that plug into there, zero, nada, zilch

the Lock Cylinder connects to a plastic gear called an Ignition Switch Sector which looks like a half circle with teeth on it [pronounced "The Part That Usually Fails"]

The Sector Gear connects to the Switch Rack Assembly made out of what seems like the world's finest shinny pot metal, kinda like a rack and pinion steering concept a round ball makes a 2x4 go side to side or up and down concept

The Rack connects to a Switch Rod, basically about a foot long metal coat hanger looking thing with two hooks one at each end, this works like a push \ pull device

So far we covered five components, Key, Cylinder, Sector, Rack, and Rod and no wires to speak of, see MECHANICAL

finally the Rod connects to the actual Ignition Switch, now this switch actually has two funky looking plastic connectors which plug into it, in my case one plug is white and the other black yours may differ

So I like to think of this as an old lazy man sitting in his lazy boy and using a broom stick to turn the light switch off and on located just out of reach on the wall next to him ~ how's that for an analogy

And this my friends is why these vehicles were / are so easy to steal, and I speak from experience... no I do not steal cars, I had one stolen. You see all you have to do is get ahold of that metal rod maybe cut it and push it down and whalla vroom vroom vroom truck is running
