Help identifying dead electro. cap polarity?
 

This cap was removed from a 70's-80's German industrial machine:

http://i37.tinypic.com/10psxg3.jpg

It has no polarity markings. One terminal is common with the metal case. Is
this always an indication of the (-) terminal?

The base has molded terminal locations numbered 1-4, two of which are empty:

Markings on the side a

B41111-B7108-T
1000uF 40V-
GERMANY
GPF DIN 41332 06.78

I find a few references to a Siemens part that is similar:

http://www.screenghost.com/shop/show.asp?ID=74#

but no datasheet can I find. Can someone more resourceful than I find one?

I cut open one of these caps. It is paper & foil (or so it seems) spiral wrap
construction. Can polarity be determined by internal construction? Is the
center terminal always one pole (ie, always +)?

Thanks.

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".

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

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

Thanks!

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.

** Nonsense.

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

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.

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.

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

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.

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

How is it wired in the circuit? When in doubt, this is what I look at.
You can also substitute it with an AC rated cap and just measure the
voltage across it to find out which way around it should be.

For modern capacitors, yes, *BUT* there were some chassis-mounted
caps with POSITIVE (outside) cans/cases.

And then
when they make a 7 they always add a cross through the middle... so as
not to confuse it with the one.

The Germans (and those in many other Continental European countries)
certainly do that when WRITING the number 7. However, I can't recall
ever seeing it on a PRINTED 7. This is (of course) because they start
writing a 1 (one) with a long slanted up-stroke, followed by a vertical
down-stroke. As such, it's not unlike an 'artistically' written 7. The
addition of a horizontal stroke through the vertical down-stroke of the
7 prevents it from being confused with a 1. With a printed 7, the top
stroke is definitely horizontal, and there is no confusion.

Most non-Europeans write a 1 (one) as a single vertical down-stroke, so
there is no possibility of confusion between a 1 and a 7. However, if
you decide to embellish a 1 with the short slanted up-stroke at the top
and the foot at the bottom, you have to be careful that it cannot be
confused with a 2.
