2x Fluorescent Bulb Circuit
You are currently reading a thread in /diy/ - Do It yourself
New to electronics. Anybody have any idea why I can't fix this fish tank lid? It has two fluorescent bulbs.
I've replaced;
- The bulbs themselves
- The lamp starter switches.
- The ballast.
.. and it still won't work.
If I touch the lamps to power, then they flicker so I know there's power. As soon as I put them in the fittings properly they switch off. Which part is going wrong here?
Sorry for bad quality photo/diagram.

Being in a fish tank lid I'd suspect corroded sockets.

Nope. Sockets are fine. I've used a voltmeter on the last starter switch in the circuit & get a reading, so presumably (unless I'm wrong) that means that at least the first bulb should be lit up?

I've only changed out 3 ballasts before and I could have sworn that the lamps were parralel with ballast? Not sure if that would matter
if touching it helps there is a good chance there is nothing grounded near the bulbs
for some reason flourescent lights dont strike well unless there is something grounded near them. your finger is a crappy ground but it helps. Try running a grounded conductor near it and see if they fire, if they do install one.
