If you have over-charging you need to check the orange wires that are spiced together just on the main harness side of the ignition switch plug. Three orange wires come together there with a crimp connector. I cut out the connector, the crimp and soldered these wired together (not one big blob of course). Charging volgage is a tad over 14.5 at the battery, all is well.

I don't see where to add pix, you need to cut back the wrap on the harness and your find white wrapping that is over the 3 orange wire crimp.

I wonder if the 89 1100 has the same wiring setup as my 89 750?

nothing special between motor electrical, pulse generator coils and starter. Done the alternator may be the odd setup. Check the wiring diagram.
