  The SUSY Ward identities (WIs) for the N=1 SU(2) SUSY Yang Mills theory
discretized on the lattice with Wilson fermions (gluinos) are considered. The
study is performed in the framework of a Monte Carlo simulation of the model
with light dynamical gluinos. The renormalization and mixing constants of the
lattice SUSY current $Z_S$ and $Z_T$ and the additively renormalized gluino
mass $m_S$ are unknown parameters of the SUSY WIs. Using suitable on-shell
combinations of the WIs, the ratios $Z_T/Z_S$ and $m_S/Z_S$ are determined
non-perturbatively at one value of the coupling constant $g_0$ and two values
of the hopping parameter $\kappa$.
