you defo got power to the unit???

i hate strip lights!!! if the ballast and tubes don't fix get new light much easier than faffing about!!! used to be my method in last job...! ballast what £20 each x 2 + Lamps + Starters = New Fitting!!!

for a wiring diagram look at the ballast normally printed on there , also make sure you got the correct starter , in the older fittings its very often the end caps that fail ,i change ballasts when i can but when its an old fitting na just replace the fitting

guys a new unit is £60. why throw away a thing that can be fixed. would u chuk ur car if d lights failed

well your fluorescent is only running on 2 cylinders and if its an old'n i'd get rid.

Newer ones are more efficient anyway so in the long run = less CO2.

Are any of the lamps working ? because what you have is in efect 4 seperate fittings.

If none are working then DurhamSparky is probably right or you have a loose connection on the supply side.

2 working and as i said i repleced 2 x ballast, 2 x tubes, 2 x starters. still no go.i just wanted to know what a good spark would do b4 binning it. i know the easy way is dump and buy, after all its not our money going in d bin. is there any real pride left in this job. we are supposed to be able to fault find

Can I take it that the 2 starters, tubes & ballasts you changed are the ones that don't work ?

If so, is there an internal fuse for each side of the fitting? if not it will just be an internal wiring problem. You've already changed every component it could be.

 

[DurhamSparky]

check the soldered / push fit connections in the Caps at end of the lamps/tubes...!!! i

This may sound silly but some fittings are wired with 2 lamps in series so if one lamp doesn't work both lamps won't work.

Have you tried a known working lamps in the terminals that aren't working?
