mmm the dreaded theory side
i would guess that 90% of us have forgotten 90% of what we learned at tech,

so the reason behind this thread is a sort of revision of what we already know

so i`ll start of with DOL starters and a wiring diagram if you what info / wiring diagrams please ask via PM /email otherwise this thread will be chocker with chit chat and it`ll slow down others wanting info


SO DOL starters and a wiring diagram

lots to read here bring a brew and a sarni along

electrical motor theory AC & DC

another one that requires several brews to complete

what exam is this?? I thought I just needed to do the wiring regs course and get me ARTC??:curse: I think if I have to jump through any more hoops I'll just go home and earn some much needed cash

as past of the new vetesses route sparks have to do a practical exam of which approx half is theory hence the thread

oh so i'm ok then, thank god for that! I'm waiting for my ARTC result hence i'm a bit twitchy lol

Thanks Steve you are so helpful my OH will I am sure enjoy looking at all of this over a cuppa. Thanks again.

Hi Jamie sorry for buttin in but whendid u apply for your ARTC? We applied over 3 weeks ago and still havent heard anything?So rather nervous that my oh might still get a phone test in the middle of the night

Praise and adulation are only accepted if accompanied by copious amounts of beer

If we were in good old Oz in the sunshine I would certainly get the beers going, but as we're in battered Britain, I can only send you back karma!!!!!!!
