My horn didn’t go so well. I don’t really enjoy mechanical work so I removed it and took it to an auto lec. He returned it and said he had repaired it but it still didn’t work. I think he tested it with a 12v battery. I took it apart only to find it shorting because the hot wire had earthed. I insulated it with heat shrink. Problem solved. The auto lec is not really a liar but I figured he just didn’t want small jobs otherwise he doesn’t want to work for gary.
Some time back I needed a home sensor light modified so I asked my friend who lives not too far away if he would do it. Yes of course he responded. As he was doing this job I asked, you are an electrical engineer aren’t you. No he replied, a mechanical engineer. I asked myself well there is any reason that I, who is not qualified can’t do it. So I did. Installations, modifications and repairs. I did buy a $10 tell tail to check for electricity prior to putting my fingers near wires. The difference between myself and tradesmen is the cost of labour.
