We use the covariant and gauge-invariant 1+1+2 formalism of Clarkson andBarrett \cite{Clarkson2003} to analyze electromagnetic (EM) perturbations onnon-vacuum {\it locally rotationally symmetric} (LRS) class II space-times.Ultimately, we show how to derive six real decoupled equations governing thetotal of six EM scalar and 2-vector harmonic amplitudes. Four of these are new,and result from expanding the complex EM 2-vector which we defined in\cite{Burston2007} in terms of EM 2-vector harmonic amplitudes. We are thenable to show that there are four precise combinations of the amplitudes thatdecouple, two of these are polar perturbations whereas the remaining two areaxial. The remaining two decoupled equations are the generalized Regge-Wheelerequations which were developed previously in \cite{Betschart2004}, and thesegovern the two EM scalar harmonic amplitudes. However, our analysis generalizesthis by including a full description and classification of energy-momentumsources, such as charges and currents.
