  We examine the stability of charged Lovelock black hole solutions under
vector type and scalar type perturbations. We find the suitable master
variables for the stability analysis; the equations for these variables are the
Schrodinger type equations with two components and these Schrodinger operators
are symmetric. By these master equations, we show that charged Lovelock Black
holes are stable under vector type perturbations. For scalar type
perturbations, we show the criteria for the instability and check these
numerically. In our previous paper, we have shown that nearly extremal black
holes have the instability under tensor type perturbations. In this paper, we
find that black holes with small charge have the instability under scalar type
perturbations even if they have relatively large mass.
