i have 4 fittings in my garage,2 didnt work,the wiring was a bit naff so i rewired it,now i have 3 that try to light,they all run from 1 switch.
any ideas?

Have you tried changing the starters

I always change the tubes (£2each) and starters (35p) together in mine whenever they start to flicker. If you have one good starter you can start them and take it out to start the next one if you're stuck for one. Once the ends of the tubes start to darken they are on the way out.

woooooooooooohoo,3 working and 1 tube needed,cheers chaps
