just to make that clear... just the person before me had bodged mine....
mine only started cutting out after i messed and disturbed it trying to fix his mess!!
so may be you have just disturbed a vac pipe whilst working on it like i did!!

ps... can ya throw some pics of your home made induction kit cos im considering it on mine!
