[QUOTE="jonnymc11, post: 174065, member: 646"] Hey all, did my am2 last week.... was so nervous, as i live on my nerves! couldnt even eat my breakfast on the days i went. Passed my job, and testing, but i struggled and failed on the fault finding. I work in the domestic enviroment, and managed to find the faults on my ring main, co2 circ, data. Have any of yous had these faults? incase i get them again, so you's might be able to point me in the right direction, of where i went wrong perhaps? I got two faults on my motor and 2 faults on my heating, which i could not find. [B]Fault - Motor: Motor will Not operate[/B] So, I thought i might have an open circuit on the Line's, or Neutrals. belled each on out, couldnt find a thing. Only thing i could not get a ring on was the incoming/outgoing neutral terminal in the DOL starter. The supply line buzzed out, but when i went to the bottom it didnt, but i dont no if its supposed to with it not being energised? [B]Fault - Motor: Tenant complains on a tingling feeling when touching the dol starter and water pipe[/B] belled everything out, but never used IR tester, possibly N-E you supply to dol starter inside the steel trunking you think? [B]Heating Faults[/B] When calling for hot water the MCB trips Boiler and pump continously running both possibly shorts but could suss out where to test between. [/QUOTE]
