Humping A1200 capacitor lugs

[scuzzb494]

Hi

I have this old Amiga 1200 motherboard that was busted when it arrived in  a tower back in 2000. I bought the tower from a guy off Amibench and he very kindly sold me a fresh 1200 motherbaord to use with the tower, which I still have. The old board was shoved up in the loft and I never questioned why it didn't work. Anyway I had reason to pop up into the loft and tripped over the A1200 amongst all my cat baskets and old clothes bags. It was only when I studied the board close up that I discovered two neg/pos capacitor lugs humping away on the board. I'd like to say I knew what they were doing but I am afraid to ask. Given that the board would have been only 7 years old when it arrived I don't think the capacitor will have naturally decayed. Maybe it blew for what ever reason.

If anyone can shed some light on what these filthy lugs are doing I would appreciate it. The board is a Rev 2B so none of the wire mods around the board. All looks pretty clean. If anyone recalls the EZ Tower had a single blue wire to the centre of the A1200 power supply being fed off the main tower PSU.

There you go. What is going on here?

PS The A1200 has had a square slot cut out of the casing on that side of the machine. Maybe another clue.

This cap is in line to the composite video out. it looks like it is meant to be shorted so that the video out works. maybe the cap was broken and this looked like an easy fix to get video back.
