Abstract Tunneling through small Coulomb islands is studied in the intermediate coupling regime based on a generalized multi-level Anderson-Wolff model. It is shown that conductance and magnetization as a function of voltage exhibit a type of the universal quantum fluctuations. We predict new crossover from the Coulomb blockade oscillations to the universal conductance fluctuations, and the Coulomb blockade oscillations assisted Kondo peaks.
