My bro is in the domestic appliance trade:
Back in 1984 my bro set up his thing in huddersfield town centre, he was shit hot with washers dryers etc,I helped him out until he got electrically certified because without that qualification he couldn't get liability insurance,and he didn't own a meggar or knew how to use one at the time.
I was a qualified electrician at the time,but have always been involved in the security industry,anyway to cut a long story short,I spent a lot of time there and Learned something new.
All that came into play (so I thought ), when our LG tromm refused to spin,"brushes i thought", turns out these don't have them.Now I didn't have a clue what the prob was now and had to get bro out who replaced the hall sensor.
Just goes to show if you are not a pro in any trade then technology leaves man behind :)
