IF there is a troll here, that will be you, that will.
It was a useful comment.
As you yourself said, you are ignorant, so advice to not fiddle with things you don't understand is not misplaced. Even if it isn't the sort of advice you thought you should get.
As I said - it clearly wasn't welcome advice.
But ingratiating, flattering, obsequious, sycophantic and fawning? Really?
I would ask you for a reasoned and intelligent explanation of why what he said was either mocking or joking, but I doubt there would be any point.
Talking to yourself now?
Speedy is not a troll. He obviously knows the dangers of 'bodging' an electrical repair.
I am a time-served armature winder with over 40 years experience of electric motor repairs, and believe me, there are no shortcuts/bodges/make-do's that are acceptably safe. You are playing with something that uses 230-240v and hoping you do not get hurt. Lets suppose, just suppose, you get it to work. As explained earlier if that piece of brass rubs the varnish off the windings the least damage it will do is blow the coils. (you are aware of course that coils, even ones that are bound together with varnish, actually vibrate against each other when current is applied to them?).
Lets suppose you are at work and your elderly neighbour/friend/relative calls round to borrow a mower because theirs has broken down. Your wife lends them your bodged up one and they are seriously hurt/killed.
How would that make you feel? You can't blame the person who lent it to them. They didn't do the repair.

I don't intend to insult or upset anyone, But, there is nothing a Duct tape can't fix...........http://www.dailymail.co.uk/travel/t...E-engine-shell-easyJet-plane-moments-off.html
There is more risk of that guy getting sucked into the engine than a plane falling off the skies.
As for this guys motor, all he needs to do is extend that wire more elegantly, sleeve it and re-attach it to post, job done safe and secure, where does the danger comes from? it would be no more dangerous than what it was when it was new.
I am not sure if people come on these forums for advice because they don't know, but if they knew, would anyone come on here and for what?
half the people don't know how to wire up a 3 pin plug correctly, but if we can tell them how to it would be more safe for all.

It's OK mike, thanks for your advice. Much appreciated. Some people who post on these forums love to get involved in a needless insulting arguments, the regular posters included. As always, best policy is to ignore them. I always appreciate warnings of safety, but when these are dressed up as a passing insult, it is just not helpful to anyone.
I am going use the method you described originally mike. It is only a 3mm gap I have to bridge.

Thanks Disman, safety is always of prime concern no matter what, no one is suggesting that you unwound the motor coils and rewound it again, as that would be beyond average skills, one would need specialised equipment and know how to do that with a correct gauge wire. This is a simple repair requiring a broken wire off the post reattached as that happened to my own flymo, and it happened to each post at two different times, I pulled some slack and managed to terminate one side Ok but the other side was more challenging as I could not tug out any slack in wire, I therefore extended it using a small metal sleeve I made out of tin sheet (used an old can of baked beans lid) I rolled a small piece over a steel pin, the pin can be a small nail, safety pin, paper clip unfolded and straightened, etc etc, and once I formed a metal sleeve approx 1/2" long, and rolled it over the pin, for forming a sleeve and using my pliers, I then inserted the broken end of the coil wire at one end about 1/4" into the sleeve, and the extension wire from the other end, and squeese it hard with a pair of pliers to clamp wires, and indent the sleeve using a blunt cutter so that it only indents the sleeve and not cut it through completely. Job done, my mover hasn't failed, hasn't caught fire, two years now, it lasted longer than the original as it packed up within 3 months into purchase from new from B&Q. Took it back, but they gave me a repair shop address about 10 miles away, and I didn't bother as it would have taken me longer to leave it there and bring it back, so luckily I know how to so i did my own repair..
Dishman if you need any further clarification or help let me know by PM .
Most lawn movers are double insulated, and do not have an erthing requirement, and instructions will tell you that you should use an earth leakage safety device (RCD) you can get a plug in one if you haven't got one on your CU, for your own safety, should the electrical cord get cut by its blades, (more chance of this happening and electrocution than by a bodged repair, as well as Instructions will say do not cut grass when it is wet.)

Where is the insult?
Feel free to be intelligent, rational and logical when explaining.
People fiddling with things outwith their knowledge, competence and understanding?
DIY be dammed - being a DIYer does not somehow give you a magic exemption from needing to have genuine expertise.
Hence the reason why we are here to give someone our expertise, in this particular case, we pointed out some misunderstanding he had where he was not sure of what windings are and he thought they were a lump of copper, we corrected him, he has learned something useful and that is how we all learned, I can understand if he was fiddling with a Microwave Oven, where Highly Dangerous 2000volts with deadly high current could kill anyone instantly, yes there are still people who will be happy to teach others how to fix microwaves, as long as all cautions are observed, this particular case of a wire broken from a motor terminal presented no danger even if he bodged that repair, because either the motor will work again or the repair to joint was of such a poor quality that the motor would simply not work or fail prematurely, I cannot see any danger in that, I have been in this game long enough to say that, it is not going to be intrinsically safe then again all motors arc across commutators, so I simply explained how to extend that wire and reconnect, hence my question where will the danger come from if he follows given instructions.
Let us not forget before we drag ourselves into this world of hyper safety, we risk our lives each day the minute we step outside our door, you don't know who is lurking outside your door ready to pump bullets in your head and stab you with a knife, you don't know who is drink and driving and ends up mounting a pavement and knocks you down, you don't know walking on a pavement and a chimney falls down and kills you outright, you don't know a large sheet of glass Mirror pane resting against a wall falls over and kills someone, you don't know if the car you were following dropped a piece of engine part that bounced off the road several times and landed straight through your windscreen and embedded into your head, all of these are avoidable if we make a legislation and ban all drivers from creating this risk in the first place, so why not outlaw driving? more people are killed in road accidents than by electrical faults or gas explosions, we need to keep things in perspective, and accept some risks, have you not heard of ovens exploding ? do we all stop using ovens? the other day i had a narrow escape when I stepped outside my house and a cyclist riding on the pavement whooshed past me, and due to a hedge I didn't see him coming! yes he should not have been riding like a mad lunatic yet my life was inches away from death.

Dishman can bodge his mower as much as he likes , but if it injures someone else or damages their property , it's not acceptable. I have visions of someone taking mowers etc out of skips, bodging them up and selling them on Ebay. I hope I'm wrong
I don't think Dishman is anyone other than a genuine guy trying to fix his broken mover with our help and guidance, however i see your point, but as I said life is full of risks, you could slip badly over a slimey snail or fallen rotting tree leaves in your garden path, and bang your head against a paving slab, or some other sharp object, you could end up getting a minor injury or even a fatal injury and die, how much can a small electrical mover harm anyone more than a mobile phone charger catching fire and exploding setting your house on fire, do we stop using chargers? it is likely that some chargers even well built and well designed with all safety aspects can and will from time to time fail and go wrong, the very safety device itself could be faulty during manufacture and failed to protect, hence why we even have insurance. A couple of years ago an old women who was eating fish died of a fish bone stuck in her throat and killed her! where do we draw a line of safety, do we ban everyone eating fish as it could prove fatal.
I am not having a dig at anyone, but let us evaluate risks, everything in life is risk, even the air we breath is a risk, what is in it? is it harmful to our health? you will find hundreds and thousands of cases where people have lost their lives for very silly and small reasons, Micheal Schumacher suffered a serious head injuries in a ski accident, a formula 1 champion who had been skiing for years suddenly got into trouble and ......just a question of being in the wrong place at the wrong time, poor Jo Cox going about her business....was she expecting that her life would end in a tragedy? do we now start providing all MPs with armoured body suits and armored bomb proof cars?

Rest assured DaveHerns, that is not something I would do nor condone. Not that I have to defend myself, but this was given to me as a spare (to see if I could get it working) for me to use. I am not a electrician, but I have done my fare share of replacing carbon brushes, rewiring plugs, putting in new light fittings. I have stripped my hedge-cutter to repair/replace the cable on the safety switch and rebuild the gear mechanism (now works perfectly). I also repaired the micro-switch on my other flymo, which had actually become dangerous (the mower would turn on immediately without input) which again, now works properly. The advice that Mike has given (who actually helped me find the fault) seems logical, safe and simple enough to be within my skill set (in my own judgement). If others on the forum do not like that, it is not my problem, it is my risk to take.
While I appreciate those who come on for constructive advice and even criticism or warnings of safety. Others seem to feel that being critical also requires provoking people into pointless arguments, none of which I really have time for.

Indeed.
But what isn't yours to do is to call someone a troll, accuse them of insulting you, mocking you etc, when they give you advice which you happen not to like.
Saying to someone or in this case to the forum "Darwin award candidate in the making" is in my view hardly constructive. It is calling someone "stupid" and it is mocking them. You may not read it that way, but I did. I am quite within my right to call someone out on it. Again, I refuse to get drawn in a debate or an argument.
-just seen your further post... which proves my point...-
Again you cannot help yourself with your "gene pool" comments. I do not need to say any more on the subject as it is clearly not worth my time.
