I've the 330SD which may be the one before yours? I've the manual and wiring diagram for it if its any use? You wont find much online, I tried and failed for a long time with mine. Its is up to s/n AG300636. If yours is later than this, I'd email morris machinery and ask them. Steve Bird is the man. fairly helpful, took a bit of persuading to get the paperwork but he didnt charge me for it which is cool!
If the wiring looks ok and you are sure the fuses haven't blown, is there a trip on It the push to reset type? Or it may be that either the avr for the 110 has let all the magic smoke out or a capacitor has gone and done as above. Not sure of that particular model which it has, if you have opened it up did part of it smell electrical deathy if so that is the best place to start!
