cheers vic, yes it was the ballasts but it was funny as the lead mechanic was a little indian guy(who was a otis freak. he knew 401's backwards and could strip a selector blindfolded!) and he went off his tree! he said 'so if the globes didnt fix didnt you think to keep going to find the fault. how are you going to fix a lift if you think like that!'
you sound a lot like our company. alot of companies over here have gone down bc they have got to big too fast. we have 7 service rounds with about 90 units on each plus we install spanish lifts to about 50 a year with about 30 blokes on contruction.
