I have a Bonneville T 100 -2003 and my neutral lamp is not working . My tacometer is not working either and my local Triumph dealer say it is diods that are broken but they do not know where they are located. They say that Thriumph them selves do not know where they are. Is there anybody that know where I should try to find them. Do not want to cut up all Cable harness. Best regards Ola
The neutral light could simply be the bulb. Have you checked? The switch screws into the floor of the gearbox with a simple tab. The switch rides on an internal rod with a cutout section. Likewise the tacho may have a simple cure. It is driven by a signal from the igniter. If the bike runs ok you can replace the igniter feed with one from the 12v to the coil. Just run a wire taped to the loom round the headstock.
The diode pack is taped into the harness under the tank over the valve covers. The diodes are plugged into the white clip.
