  We investigate a reliability of the hypothesis of exact conservation of the
charged weak hadronic vector current in the neutron $\beta^-$-decay with
polarized neutron and unpolarized proton and electron. We calculate the
contributions of the phenomenological term, responsible for Exact Conservation
of the charged weak hadronic Vector Current (or the ECVC effect) in the neutron
$\beta^-$-decay even for different masses of the neutron and proton (see
Leitner et al. Phys. Rev. C73, 065502 (2006)), to the correlation coefficients
together with a complete set of contributions of scalar and tensor interactions
beyond the Standard Model (SM). We argue if total contributions of scalar and
tensor interactions beyond the SM (Phys. Rev. D88, 073002 (2013); arXiv:
1212.0332v4 [hep-ph]) will not be able to reconcile the experimental data on
the correlation coefficients with the contributions of the ECVC effect, one may
conclude that the charged weak hadronic vector current is not conserved in the
hadronic transitions of weak processes with different masses of incoming and
outgoing hadrons.
