RE: Charging
If the wires are connected, then I am at a loss as to what to do next.
It sounds like you have everything hooked up correctly. The next thing I would do is check the output of the generator using an ampmeter and following the procedure.
If the generator checks out OK then I would just ride the bike and not worry about the gen light not functioning........pg

RE: Charging
Has the bulb been verified good? Not sure of how the no-charge light works exactly, but I believe a diode is involved. Could this item be bad? (I think if it were, the light would be on all the time...) Mine doesn't have such conveniences, so I'm completely guessing here.
Got continuity on all the wires?

RE: Charging
The 77 has a diode wired into the circuit and they have a habit of one of the leads breaking off because it's located in the headlight bucket and everything gets cramped in there with all the wiring and the headlamp itself. Remove the light and look for a wire with an orange sleeve around part of it. The diode is in this sleeve. It will be held in place with wire ties. Bypass the diode and see if the gen light comes on when you turn the key on. If it is the diode you can get another at Radio Shack or maybe the local Harley dealer might have one in stock. Be sure to take note of the number on the old one and the orientation of the line and the arrow on the old one. It has to go back in the same way or it won't work. Be gentle - the leads break off easily. I found a computer circuit board that had a bunch of the same number diodes on it so I cut them off and have a bunch of spares although the leads are shorter. If the diode is open or the lead broken off, the gen light won't come on.
