The Caps are here! The Caps are here!

Actually, they arrived a few days ago.

I was all set to reward myself with some old TV work after doing a bunch of less-fun stuff over the past few days. So I warmed up the old soldering iron and sat down to work...

...And quickly realized that I had forgot some of what I had taken apart a few weeks ago...

I had unsoldered two capacitor cans, and now I can't be sure how they were installed. One was a 160 mfd can, and the other was a 160mfd/80mfd can. I did label the leads, but here's the problem:

One of the leads was soldered from one terminal of the 160mfd can, to another terminal on the other 160mfd/80mfd can. I labled them both "160mfd".

Here's a pic:



Now one of these I marked with a square (as per the can) so I'm pretty sure it leads to the + side of a 160mfd cap. However, the other lead is simply marked with a triangle (again, per the can). I might assume that this side was the - , but why would there be TWO leads to negative?

As was mention by someone else earlier, one of these cans does not "ground" to the chassis... Should I assume the others do?

Can someone tell me if this is correct:

Lead labeled 80mfd connects to the + side of an 80mfd cap, - side of cap to chassis.

Lead labeled 160mfd (square) connects to the + side of 160mfd cap (I actually already did this in the photo) - side of cap to ??? (Because this cap was not grounded to chassis)

Leads labeled 160mfd (triangle) connect to ???

This is damn hard to explain in a written post...
