Just did a fuse replacement of the red 10 amp fuse and totally fixed the charging problem for a $1.39 fuse. A few suggestions:
1. I used a small wood chisel to pop off the plastic end caps. Easy.
2. You do need a narrow, long torx bit to get out two of the screws. I ground my bit down on a surface grinder holding it fast with vice grips to make it narrower. It worked.
3. I found it easier to slide the whole battery pack out and access the fuse with it out. The 10 amp fuse is on the end where the plug in charging port goes. Use a utility knife to cut the black glue/adhesive on both sides before sliding it out.
4. A utility knife also works well to slice open the plastic wrapper.
5. Once the fuse was swapped out I used standard electrical tape to tape things back. I then coated the patched area and the tape with liquid electrical tape for a good seal. This brushes on nicely.
6. Test this before reassembly. Charger lights should both be red now.
7. Start to finish this is a 30 minute project with the right tools.
