Is there a starter? - 35p each, I'd try this first

Thought the same, done that.

So you've got switchstart fittings. Then it's wrong
starters,
bad tubes or bad contacts. The capacitor can't cause
this.

Corse it can.

And is in fact by far the most likely problem when the
tubes
arent connected in series after the things he has tried
already.
The capacitor will be across mains in.

Yes.

Good, we have got that far.

Can you explain, assuming the supply impedance is in the
order
of a
fraction of an ohm, why a capacitor can cause the
perturbations in
voltage supply to cause a substantial flicker?

You havent established that it is causing perturbations
in the
voltage supply. And it can obviously do that by not
being a
viable cap anymore anyway.

Is that an admission that its not the capacitor?

Nope. If the tubes arent in series, that is by far
the most likely cause of the problem given
what he has tried that has made no difference.

Or are you thinking of some other capacitor characteristic
that
might
cause this flicker,

Failure mode of electros, yep.

Electros? Is this a new component technology?

Certainly electrolytic capacitors are rarely used across AC
mains, so
it must be some other capacitor technology.

if so do tell.

Most obviously if its got a significant partial short
now, as electros sometimes do when they have failed.
That could easily see the tubes no longer getting full
mains voltage anymore, and so flicker now.

Are you now suggesting this partial short will be causing
perturbations on mains voltage?

Nope, reduced mains voltage across the tubes.

And I didnt say WILL BE, I said IF.

Previously you said we haven't established that such a
"partial
short"
would cause "perturbations in the voltage supply".

Everyone can see themselves that I said nothing of the sort
previously.

You really ought to make your mind up.

You never could bull**** your way out of a wet paper bag.

Is that your answer to a question you have failed to answer?

Everyone can see for themselves that the question was
answered, you pathetic excuse for a lying bull**** artist.

You said it could be the cap. I have asked how:
"Can you explain, assuming the supply impedance is in the
order
of a
fraction of an ohm, why a capacitor can cause the
perturbations in
voltage supply to cause a substantial flicker?"

Everyone can see for themselves that the question was
answered, you pathetic excuse for a lying bull**** artist.

You are incapable of providing an answer as to how a faulty
capacitor
can cause flicker.

Everyone can see for themselves that you are lying
thru your ****ing teeth, as you always so when you
have got done like a ****ing dinner, as you always
are, you pathetic excuse for a lying bull**** artist.

Are you now denying your reply of "Corse it can."

to "So you've got switchstart fittings. Then it's wrong
starters, bad
tubes or bad contacts. The capacitor can't cause this."

Nope, the cap can cause what he is seeing.

Once again I ask you to explain how, given the low impedance of
supply, even lower since it will be for lighting.

You have no idea what the impedance of
the supply is with that PARTICULAR fluoro.

Most supplies are a very low impedance,

Most is irrelevant with faults.

How much power would be dissipated in a faulty 'electro' to cause a
meaningful fluctuation in voltage?

Depends on the state of the supply to the fluoro.

We have established that a 3% drop is acceptable, so for a 6Amp
circuit that equates to a max fault current of 200Amps. Lets be
generous and say we're looking at a 10% of this, say 20Amp at 240V


That aint a FAULT condition.


So how much current and power is your 'electro' taking to cause flicker?


Irrelevant when removing it stops the flicker.

How long would you say an 'electro' would last given that "Both tubes
in a flourescent are flickering and won't light"?


there is also the 3% limit of voltage drop for a lighting circuit.

Also irrelevant with FAULTS.

What sort of fault would you have in mind?

In what gets the mains to the fluoro.

Yes read above.


Completely useless, as always with your mindless silly ****.


You can read?


You can certainly lie and bull****.

Is this your way of back-pedalling

No back pedalling at all.

Clearly you're just unable to explain your assertion.

It isnt an assertion, its a fact and when someone like
Adam has seen it, doesnt need any explanation either.

You mean you can't explain it?

Everyone can see for themselves that I did,
you pathetic excuse for a lying bull**** artist.

And rubbed your stupid nose in the FACT that there is
no need for any explanation when its so trivial to remove
the cap and see if its what is causing the problem after
the more obvious possibilitys have been tried first.

'stupid nose'? If its so trivial do explain.

No point, its been seen by someone with a clue, Adam.

What has he seen?

You came up with an assertion, not a fact.

Its is a fact that a bad cap can produce what he is seeing.

Then explain the mechanism how an 'electro' can cause flicker?

No point, its been seen by someone with a clue, Adam.

Just because Adam has 'seen it' it must be so?

Yep, when he has seen a bad cap do that, that is precisely what it
is.

Then explain the mechanism how an 'electro' can cause flicker?

No point, its been seen by someone with a clue, Adam.

Do you see him endorsing your assertion with an explanation?

Dont need any explanation, just observe
that removing the cap fixes the problem.

And the explanation for why removing the
cap fixes the problem is so ****ing obvious to
anyone with even half a ****ing clue anyway.

Then explain the mechanism how an 'electro' can cause flicker?

No point, its been seen by someone with a clue, Adam.


You made the assertion.


I stated the fact that a bad cap could produce the symptoms seen.

Adam said "A duff one could cause problems". He used the word "could".


Because he had seen that happen.

You said "Corse it can" some time earlier.


Duh.


Ah, so you're seeing the light after all?


More of your lies.

That you said "Corse it can" to "The capacitor can't cause this".


Because it can and does at times, ****wit.

All it needs is to rub your stupid pig ignorant nose in
the FACT that a bad cap can produce that result and
given its so completely trivial to prove if the cap is
the problem in this particular case after the more
likely possibilitys have already been tried, only a
terminal ****wit such as yourself wouldnt try it without
the cap and would demand an explanation first.

If its trivial to prove an "electro" can cause flicker, do tell.

Just did. Remove the cap, it doesnt flicker anymore, ****wit.

Who said the cap was removed?

Thats what you do to see if that the problem, ****wit.

by calling me a "lying bull**** artist"?

Thats not calling you anything, its a statement
of fact as everyone can see for themselves.

You start calling people names when your knowledge is lacking or
you've lost the case.

I call lying bull**** artists lying bull**** artist when they
lie thru their ****ing teeth as we can all see you doing.

I don't see how asking you to explain your assertion is a lie?

I never said that THAT was a lie, you lying bull**** artist.

You called me a liar

Yes.

because I asked you to explain your assertion.

Everyone can see for themselves that you are lying
thru your ****ing teeth about that. Its still there in the
quoting, you pathetic excuse for a lying bull**** artist.

What am I lying about?

I told you in the next sentence, ****wit.

Which sentence?


The NEXT sentence, ****wit. It isnt even a big word, ****wit.


Don't you know what I was lying about?


I said what you lie about in the next sentence, ****wit.

Is dementia creeping in?


You've always been brain dead, no creeping involved.

You lie was about what you claimed I had said, you lying bull****
artist.

You claimed the 'electro' can cause supply problems.

Everyone can see for themselves that I did nothing of the sort,
****wit.

Everyone can see your reply of "Corse it can" to "The capacitor can't
cause this".


Duh.

Or are you now denying this


Nope.


We have moved a long way!


You are lying, as always.

and still calling me a liar?


Yep, but not about that, ****wit.


About what then?


I already told you, repeatedly, ****wit.

Until you can explain how a relatively small capacitor can cause
supply anomalies to cause flicker by an "electro" your statement
of
fact"

Its a fact that Adam has seen a bad cap produce that, ****wit.

I don't see him explaining how a faulty 'electro' can cause flicker,
do you?

Doesnt need to when removing it stops the flicker, ****wit.

I keep asking you how an 'electro' could cause this flicker.

And I keep telling you that its been seen by someone with a clue, Adam.


reams of your **** any 2 year old could leave for dead flushed where it
belongs
