Triumph Motorcycles Bonneville T100: Removal Of Alternator To Main Harness Connector

Recall Summary Triumph Motorcycles is recalling approximately 4,030 motorcycles from multiple 2016-2019 models because the connector between the alternator and main wiring harness can overheat and deform under certain conditions. When this happens, the alternator may stop charging the battery, causing the bike's electrical system to shut down while riding. The affected models include the Bonneville T100, T120, Scrambler 900, Speed Twin 900, and Street Twin, among others, distributed in the United Kingdom.

Units affected: 4,030

Reason

On affected vehicles under specific environmental conditions a localised high impedance area can occur within the connector leading to high current though small contact areas. This can lead to excessive heat causing the connector to deform. In this event the alternator may not continue to provide energy to the system which may lead to a low battery warning and cause the bike to power off as well as potential thermal/degradation concerns. Remedy: Removal of Alternator to Main Harness Connector.
