Definitely something wrong Mozilla. You do realise that the switch is up for on and down for off?
No, I did not realize that fact. For many years I've been stumbling along without devoting a lot of effort learning these little niceties.
Here is my rather primitive system for dealing with two position switches:
When I want to invoke a particular function on an automobile (or other device) I simply move a two position switch from one position to the other. In my experience, if one position is off, then the other is on and vice versa. With an indicator lamp or other obvious reaction to use as a guide, it usually doesn't take me too many tries to determine if I'm turning a particular function on or off.
If, on the other hand, I'm expecting a particular reaction and nothing happens when I move the switch to one position, I immediately move it to the other position and observe the response. If nothing happens there, I try, try again. Eventually, after several attempts, if the expected reaction is not forthcoming, I suspect something might be wrong. Normally, this epiphany happens pretty quickly. After all, there are only two positions, right?
Perhaps it's something obvious and sometimes it's not immediately so obvious. For example, if the main headlamps and parking lights are off, moving the front fog light switch will not result in the fog lamps illuminating on most cars. Not all cars mind you, but most. Or, sometimes a fuse is at fault or perhaps a defective bulb is the culprit.
In the case of my cruise control, I haven't yet determined what is wrong. They say the definition of insanity is doing the same thing over and over again but expecting different results. I'm slightly embarrassed to admit that I tried my cruise control switch in both possible positions more than once. In fact, I may have moved it back and forth more than ten times. Please don't tell anyone about this.
In summary, as a driver licensed for more well over 50 years, this simple approach to things has worked pretty well for me. At the moment I regularly drive two different cars and two different motorcycles as well as a variety of agricultural equipment. I also operate a wide variety of power tools, welders, household lights, stoves, televisions, automatic gate openers, radios, CD players, computers and their associated accessories, etc. In the past I made my living flying fighter aircraft at first and later on, large commercial airliners. In almost every case, these items have one or more two position switches.
I confess that I haven't properly memorized which way is which for most of them except for various aircraft where switch positions are usually standardized to avoid, or at least reduce, any possible confusion. Up until now, I certainly wouldn't have made a bet as to which way was ON for the Alfa cruise control switch.
In spite of this personal shortcoming, I manage to operate all this stuff pretty well, even though from time to time I find myself having to move one of these switches to the opposite position from what I thought was the correct one.
Nevertheless, I appreciate your help. In the future I'll try to remember "up is on" when it comes to the Alfa cruse control switch.
Thank you for your help.
