Wiring loom

Even in the face of strong Japanese competition the wiring looms of all Laverdas take some beating. In many ways they are better because the Italian loom is made with the engineer in mind — in other words, it is actually possible to disconnect some of the connections and still live to tell the tale.

The wiring loom on the Twins and Triples is nicely designed and tidily executed. Top quality wiring, connectors and fittings are used, the majority of them being supplied by Bosch from Germany although there is obviously some Italian and Japanese equipment.

The loom is plastic covered and rims around the frame in the best places. Check that it does not chafe anywhere. Perhaps the most prone area is around the steering head where the wires have to constantly twist and turn and yet hide under the nose of the fuel tank and behind the headlamp. If I can be critical of the loom at all it is that it is just too tight and too well hidden.

The following are places to watch on all machines: spade tags to coils on the Twins; wiring up into the instruments; front fuel tank mounting; underside of the rear mudguard to the tailight; flasher earths to their stems; wires into the central junction box; wire into the alternator on Triples.

The following are points to watch; if a connector does not snap apart« easily, it isn't a connector; always use nylon cable ties, never metal or tape; never make a 'twist the ends together' repair — use either new snap connectors or solder; always cover any joining of wires either by PVC insulation tape or plastic covers; don't put wiring through sharp bends; don't add electrical accessories unless you are able to wire them and mount them as the factory might have done.

In the event of some failure, first check out the colour coding with the appropriate wiring circuit diagram and then use a continuity tester in the form of a screwdriver type of instrument which lights up when a circuit is found. Don't tear anything apart until you have done this. Then look first for a break in the obvious places, then in the unobvious ones and then for corrosion and a short. (Some machines may be incorrectly wired for main and dip beam operation. It is of no consequence, however).
