Good point here, it can also be EXPEN$IVE! There are online sources for the 15A 600V fiber fuse most newer Flukes use, but to find one locally might not be so easy. Even some of the larger electronics supply sites charge ~$20 for this fuse!
I agree with those who have suggested you test the speed controller. If your battery is fine on the bench (probing the battery leads with your DMM) then there is a good chance this is related to the problem you had with your phase wires. Have you tried opening up your speed controller to check for obvious signs of damage/heat?
