1997 Guzzi 1100 sport i. Tail lights, brake lights, turn signals, fuel light & guage lights do not light. Have checked fuses, relays, bulbs & breaks in wiring harness. Every thing else works fine. Any suggestions will be appreciated. Thanks.

I suspect you have no power on Fuse 6 & 7, check with the key on.
These two fuses are powered from a separate contact of the ignition switch.

The grease inside the ignition switch (item (39)) goes hard with age sometimes hard enough to hold the contacts apart, if you find no power at the two fuses that's where I would start looking.
A friend with a LeMans found the wire had broken off the switch, wires tend to break off if they flex near a soldered joint, the loom should be loose and twist over several inches at that point.

If you haven't cleaned the switch in a few years pull it apart, wipe out the old grease using just a dry rag or paper towel and replace it with fresh Vaseline.
You should be able to unscrew the switch block from underneath leaving the key portion in place. It plugs into a 4 way connector (38)

BTW DON'T use di-electric grease, it will do more harm than good.
