The handle bar switches on the Guzzi gave up in July this year, parked the bike, as the heat was too much for me with the amount of work involved .
No OEM switches are available and the aftermarket combination circuit switches would not fit onto the handle bars, they are like clip-ons, but are factory original .
Finally got done with it today, third day of work .
The job took too long, due to the wire colors on the bike and wiring diagram didn't match !!!!
I added three switches to the left hand side of the small fairing, one for tail light and indicator internal lighting, and one each for head light low beam and high beam .
The original wiring on the switches was way too small for the job they had to do .
With the original switches, I would get a 3 volt drop on the bikes voltmeter when the tail light and indicator lights were turned on .
Now, about at best, a needles width of movement when the switch is turned on .
Put the headlights on a relay circuit, where the bikes headlight circuits activate the relays and you get battery direct voltage, on larger gauge wires .
Head lights seem brighter, but have not had the bike out when it's dark .
