Help identifying dead electro. cap polarity?

"Sparky"

The usual cause applies ?????

FYI:

The markings are clearly 1, 2 and 3 with the fourth a NEGATIVE sign !!!!!!!!!!!!!

Is not the negative sign *right next* to the pin linked to the case ?????

To me they look like "1" (not a "-"), "2", "3", and a really weird "4".

But with your help along with the one pin (yes, it's the (-) one) in common with the case pretty much confirms polarity.

Thanks!

Nighty-night! Lights out!

Are they? Their order is a bit strange if so.

On the other hand, take the - to be a 1, and the other symbol to be a 4 with a bit missing, and you have 1, 2, 3 and 4 in a normal order. So the situation is far from clear enough to form a basis for installing a replacement.

The stroke on the " 1" has been made longer to avoid confusion with the " - " sign.

You stupid, grossly autistic bitch.

F*ck off.

AFAIK Germans always write a ONE with a tag ( opposite 2) and a 7 with a tag through it that makes it look like a lower case t. So I suggest the - really is MINUS.

TTman Inscribed thus:

I agree ! That is how I read it.

If you *really* can't identify polarity from the part, trace the circuit back to the rectifier, another cap or dc input to the board. Or, solder a non polarised cap of a few uF to the board, power up and check with a meter. The fact that it's lower uF than the electrolytic is unlikely to damage anything...

Almost always, but ISTR reading warnings that occasionally you come across one made for use with a negative supply rail, when the can will be positive, so you're right to make sure.

However, in this instance I agree with other posters that the markings indicate that the can is negative.

Chris

Me, I'd guess the terminal marked with the '-' is negative, but that's just my warped thinking.

\\ I don't set a 4 or part of one. Yes the number pattern seems non conventional but what is conventional in electronics?

Ahh but it's german. They make the 1 with that little hat. And then when they make a 7 they always add a cross through the middle... so as not to confuse it with the one.

Take your meds.

This is how right-pondians write the numeral "1". They also cross their "7"s. ;-)

Wrong. Rigt of the English Channel, not of the pond.

North Sea in fact

Sometimes cross a 7 if the need arises, but it's not so common in the uk as it is on 'the continent'.

We may have signed up to some of the eu insanity, but we are far from hearts and minds for the revised 1000 year reich / european federal superstate / new world order :-(...
