HP67 black cable broken

[Geoff Quickfall]

First, always take pictures as you disassemble. Now that the lecture is finished :-)

The solder point directly adjacent to the red +ve power wire immediately to the right in the first photo.

Also, is that blue copper sulphate residue on the other solder points? If so clean it off before reassembly.

A caveat, their are a few different circuit boards floating around and the contact of -ve and +ve may be reversed. Since the red wire is still attached it is obvious in this case. More need to photo all aspects during disassembly!
