I have a Duratrax twin pulse charger. I tried to charge my batts and only the right side is charging. I checked the rear fuse and is ok. I took the thing apart and low and behold there are three more fuses inside. the one on the left side was burned out. It is a mini glass fuse but it is a 10amp 250volt fuse. I tried to get one at radio shack but they don't go up to 10amp only 6.5amp. I tried Home Depot with the same results. Anyone know where I can get this type of fuse?
