Hi again and thanks for your help. Have checked continuity and all 3 stats ok - but on further checking have found that terminal 5 on the heater relay which has a double blue wire attached has a melted connector and burnt wire. Not sure where the wires go but it looks like up to the blower motor and not the heater. The blower has been working when I've run it but the burnt relay terminal probably accounts for the burning smell. Any idea why this has happened and do i need a new relay or can i just get a new connector for the blue wires? - Is it likely that there's something else wrong that caused this? Doesn't look burnt or melted anywhere else and i did think the blue wires were quite loose so maybe it wasn't connected properly which is why it has failed. Heater relay doesn't look damaged just a bit burnt on the metal post but rest of box ok.
I also am concerned about the ampage - i bought the machine believing it to be converted to a 13amps but wonder if it is still 25amp which could explain running probs - how would i be able to tell if it has been converted? Thanks so much for your help so far in getting to the bottom of this and sorry for all the questions - hopefully am much nearer to fixing it at last!
