Italian electrics on the new bikes has improved and some of the switch gear seems to be the same as Japanese. All old bikes seem to have issues with electrics. As time has moved on, there has been a improvement in reliability.
On my California II the electrics have been fixed. There was connections that had failed on the wiring loom which have been fixed thanks to new connectors by Greg Bender of http://www.thisoldtractor.com/ . I did repair only individual although Greg suggested to repair the whole connector. I can see that it is easier and quicker via Gregs way.
Charlie gave some brilliant advice to place the lamp holders in an ultrasonic bath. This would clean up the contacts and he recommended some http://store.caig.com/s.nl/it.A/id.1602/.f?sc=2&category=188 . Also Charlie http://www.AntietamClassicCycle.com has access to this equipment.
I have seen pictures of Charlies workshop and am envious as my working area is very small in comparison with less toys to play with.
I have been using the cali for as much as possible and the clock warning lights (sometimes called idiot warning lights) seemed intermittent. When I switched the ignition on, the warning lights would light up, possible neutral on its own or the oil would not light, or the charge light.
All seemed to have a life of their own. As I investigated i decided to start at the neutral light switch. I put a new connector on as this was loose. Made sure the connector was home firm after. Made sure the switch worked and then moved up to the dash. I found that the voltage was correct at the lamp holder (moto guzzi part number 19768680). Then took out the lamp holder and disconnected the connectors. I found them rusty so with out the use of an ultrasonic cleaner used sand paper to clean up the contacts on both sides. Once cleaned used contact spray to clean them up. Then reassembled with silicon grease and bending the tabs of the bulb so that it made contact with the copper. This now seemed to switch on every time.
On each of the lights, high beam, lights, oil warning and charge I also carried out the same process. Now when I switch on the ignition, All lights seem to work every time. It seems that cleaning the connections and making sure that they have some silicon grease helps.
Lets hope that the talk of dodgy Italian electrics is far away. Although from this time I can see that with the Japanese bikes they all suffered from electric issues in some ways. On new bikes there does seem to be improvements that we all take for granted.
Below are some pictures of the dash of the Moto Guzzi California II. The lamp holders 19768680 or dash lights are out of the holder. This is where i made the most improvement finding dirty connectors.
The other picture is where the neutral switch is located behind the starter motor.
How are the electrics on your bike?
