On the 6 wire plug from the VR white red = W = fuel pump and charge light, white = W = ignition, white blue = B = battery, black = E = earth, British for ground, white black = F = field, the stem of the Tee connector to the alternator, and white green = N feeds back to the VR.
LUV's have a weak link in the electrical system, the fusebox. The terminals the wires connect are riveted to the fuse holders. A little age and corrosion, and you get electrical intermittents. I solved mine by taking it apart and soldering the joints. Others have cleaned it with lemon juice, and others a new fuse box.
When the generator is working, you should have 7 volts on the white green wire to the VR. It should then apply 14 volts to the white red wire turning off the ''C'' light and activating the coil of the fuel pump relay under the cover by the firewall on the passenger's side. Alternator no workie, fuel pump no workie. Check everything else before replacing the VR. A couple of years ago I think went through 3 alternators from AAP before getting one that worked.
