There is a CMU (Charge Management Unit) underneath all that wrapping.
Many thanks Zumad. That might well be the DPPM unit that is mentioned in the battery system menu.

Well we may give that impression @bar2 , but I hadn't got a clue until I Googled DPPM. It seems to manage the charging of the battery so I guess that DPPM is the same as a CMU, but spelled a bit differently. Its only 4 letters different !

And really, if I I had aspirations of being technical, I could probably make a start by not frying the battery in the first place.

Given that info, it might be worth throwing good money after bad and buying a new battery. But I'd then have to solder that in too. Hmmm. I wonder if one of my soldered joints moved while it was cooling and has gone 'dry'.

See my update to post on 6th December - a few posts back.

Today, I discovered something really important. I found another way that doesn't work.

A couple of years ago I did all the pin spreading stuf. Just recently my 595 was cutting out and sometimes not turning on at all. So I had look at the plug again and found that the little tab had lifted and the negative (black cable) pin was falling/pulling out.
My fix was to reinsert it and push down the tab. I then got out my glue gun and set a strip of glue along the top of the whole plug to hold them all in place. All working reliably again.......for now!
