Sorry I haven't answered your PMs as I have not had the computer open much in the last few days (I work weekends) and I don't always pay attention to the little PM notice in the corner of the screen.
As far as a normal switch is concerned you have 2 contacts which would be input and output and they are interchangeable. You put +12 Volts on one terminal and the load (output) on the other. On an internally lit switch the light inside draws it's +12 volts from the load or output terminal of the switch. If one reverses the +12 volt input and load wires then the light inside will always have a +12 volt supply and thus stay lit all the time but the switch will still operate as normal. There is of course a 3rd terminal on the lit switches which as you know would be the ground side for the bulb.
Now if there isn't a constant voltage being passed by the switch such as a momentary then there should be an extra lug for the +12volt input for the light. That lug would be connected to the output side of the cut off relay and the light would come on or off depending on the state of the switching relay. If that wire was connected to the input side of the relay instead of the output side then you would again, get +12 volts all the time. This is more what I figure the case to be on my rig and if I were really all that upset about it I would track it down further. A little work with the volt/ohm meter would tell me what is going on.
As I am going to be installing a 500ohm shunt and wiring in a Trimetric
amp meter soon I may devote some time to it.
