If you get the 1305 error on one of your channels, try this fix:
It worked great for me, I didn't even take out the ribbon cable, just laid the top to the side. I did take out the screw next to the fuses. I bought the fuses off of Ebay for $7 for 10 fuses.

I tried tinning the end of the fuses to do one at a time and I ruined the first new fuse. The end came off with too much heat. So I ganged all 4 together and used a clip to hold them together. Placed the 4 fuses on top of the other fuses and soldered each end, worked great. And don't be like me and put the charger back together without putting the board screw back in.
