Well I thought I was aiming for those with only a very rudimentary knowledge but perhaps I've assumed too much.
But just to take the point you bring up I think you have to take those statements in context.
"break into a circuit": I give the first example of a break in the circuit by removing the fuse and then illustrate that along with "Insert your meter in series" in the same illustration. Earlier I had said "Current flows through the wires so to measure current the circuit needs to be broken and remade with the multimeter."
I thought a picture better than all the words I could have used. The problem with 'put the red lead there' sort of approach is that each sentence becomes a paragraph.
I'm sorry If it hasn't helped. What do others think?

Well, telbell, all I can say is that you should have paid more attention in science/physics classes at school!
I do recognise the dilemma Frank is in - just how basic does he start?
If he assumed no knowledge whatsoever on the part of the reader (as you are intimating about yourself) then the FAQ would have to be as big as an electricity text-book.
That is not practicable, so a happy mean has to be taken.
I have been in electronics and electricals all my working life - yet I still have to stop and think about the basics sometimes!
In the early hours one morning we were working a ghoster to get a new fork lift truck ready for a mechanical handling show at Earls court. The battery was hanging on chains from a crane, the battery was 72 volt and 600 ampere hours, not a tiddler. The battery would not fit into the space in the truck chassis. My boss got out his tape rule and checked the length dimensions which were OK. Then he checked the width and these were also OK. "It cannot be square" he said as he measured the diagonal across the top of the battery. The tape rule light up like a light bulb as it shorted out the cell joiners. He let go of it as it became a tad hot. Then the exide cell caps went into orbit as the battery was fresh off charge and gassing well enabling the gasses in each cell to explode. Some complete cell case tops were blown off splashing sweet tasting sulphuric acid over us. Then the airborne schrapnel hit the row of 8 foot flourescent tripple light fittings above smashing all the tubes. Then we were showered with falling glass and white powder. Then we ran into the gents and soaked ourselves with as much water as we could muster by which time there was nothing left of the tape rule.
A proud weld was later removed, another battery found and the truck made the low loader in time for the show.
Health and Safety? Did not exist in those days but even if it did exactly the same scenario would have taken place as we had been working almost 24 hours without a break.
Ah my life as an apprentice!

I take your points entirely and please don't take my post as a criticism of the thought and work you.ve put into it.
Same can be said of any of the very useful and helpful sets of "instructions" posted on the Forum-some will be at the right level and some not and many of them (surprisingly!) I find easy to understand. It's just that I'm not too sure of the "intended" audience when these particular Posts are put together.
Oh and "Science" dropped me at quite an early stage of my education-my leanings were towards the "Arts"......and I don't mean painting

When I wrote technical literature for a living it was important to have my target audience tightly in view. In the absence of an official line on this I wrote all my aircraft modification and technical instructions for a specific person. He was a sergeant avionics technician who had attended all the courses but little had rubbed off on him.
My checking procedure always went along the lines of now reading this how could xxxx get it wrong?
Earlier in my career I taught army students basic electricity. When introducing current and voltage its sometimes useful to use analogies with water. So voltage becomes head or pressure of water for example. Then one day because of a colleague's illness I had to take over a class of Iranians. These guys were basically from shepherd stock who found it easier to understand electricity than plumbed water.
Like teaching Iranian shepherds electrical principles, its difficult writing for a cyber audience, we don't all have the same background.

I have been thinking about a basic electricity guide and as it may be easier to write than a fault finding guide perhaps it will get written first.

Telbell, I recommend you buy some red wire for positive (+ve), some black wire for negative (-ve) a switch and a bulb holder and bulb for a torch, also a battery which is the same voltage as the bulb.
You can then fiddle about, quite safely, and make a basic circuit, red going to one side of the bulb holder through the switch and black coming back to the battery from the other side of the bulb holder. This will light the bulb. By doing this you will begin to understand how it works and be quite pleased with yourself when you do make it work.
If you then buy a multimeter you will be able to figure out, using Frank's tutorial, how to use it to test your circuit. That should give you the basic knowledge you need in order to get started, Alan.
