We present the solution to the recently derived Wilsonian renormalization group (RG) equation for nuclear current operators. To eliminate the present ambiguity in the RG equation itself, we introduce a new condition specifying the cutoff independence of the five-point Green function corresponding to the two-body propagator with current operator insertion. The resulting effective current operator is then shown to obey a modified Ward-Takahashi identity that differs from the usual one, but that nevertheless leads to current conservation.
