N* ‘s can couple to various exclusive channels with entirely different non-resonant amplitudes, while their electrocouplings should remain the same. Consistent results from the analyses of major meson electroproduction channels N  and  +  - p show that model uncertainties in extracted N* electrocouplings are under control.
