I hope this is the proper section to post this. Hopefully someone can help a noob out.
My problem is shown in the picture below:
I tried to remedy this problem by splicing that tiny yellow wire with a bit larger copper stranded wire and then soldering the new wire to the post. It's all hooked up now, but I get a 'F1' reading when I try to power it on now. I know the best method would be to just remove the yellow wire completely and re-solder a new connection at the board, but there is a good amount of expoxy/glue at the connection. Furthermore, I don't even know where to get single core copper wire that small. Please let me know what you guys would recommend I should do. I know it's a weird request.
Here is an overall picture of the guts:
