Alarm service required

Mark sent me his board.
The damage was very localised, but very bad. The capacitor I thought was labelled C1 is C19. That part of the board was destroyed. No evidence that there was a component or tracks there. The board itself is eaten through a little.
I took a similar capacitor from a donor board he sent me. I then traced the tracks and soldered links on the reverse of the board to hold the capacitor. These miniature components are terrible to solder by hand.

Pic 1& 2. Damaged board with battery connector removed
Pic 3. Board cleaned with vinegar to prevent further damage.
Pic 4 shows where severe damage was.
Pic 5 shows repair. (Probably worse soldering I've done in a while, but I couldn't manage it without burning myself!).

Well done and we'll rescued.. I assume it now works.

I appreciate just now much effort went into resurrecting this module.

In the past I was an electronics engineer, but these days would not have attempted this!

Well done again!

Thanks
Not able to test it as I wasn't taking my car apart. It's in the post on its way back to Mark. I'm crossing everything that it will work. My main concern is that I over heated the capacitor trying to solder it back on.
