Repairing circuit boards is not at my skill level, but usually it's the meter cell that goes bad on these. I would think that any good electronic repair person could do your wire repair, but would that fix the meter? It can be fixed at no small expense by Sherry Krauter and probably others, but it won't be cheap. If you can't fix it, you do have options. Sell it as it is and get a working camera (this is probably considerably cheaper than repairing yours if you send it out), get the VC meter as mentioned, or just use an inexpensive but accurate hand held meter. The last suggestion is the route I took, and it was the most inexpensive and simplest.
My CL had a non working meter, but the strap lugs were much more aggravating than that problem. However, there are half cases on eBay that allow the camera to hang in a normal manner. I bought one and loved shooting that little thing.
