Triumph Tiger Explorer XR 2017 Service Manual page 729

Tiger Explorer XR Series
Symptom
Starter motor turns but engine does not turn over
Alternator - Assembly
Note
Prior to carrying out the diagnosis, ensure the battery voltage is 12 - 13.5 V, the immobiliser system
(if fitted) is functioning correctly, the transmission is in neutral and the clutch lever is pulled fully to
the handlebar.
The high output alternator is externally mounted to the engine, and is gear driven from the clutch primary gear.
The regulator/rectifier is integral to the alternator and does not contain any serviceable parts.
The alternator features a decoupler mounted to the drive gear, which disengages the alternator from the engine
in certain conditions. This removes shock loading from the alternator which would otherwise cause premature
wear or damage to various alternator components.
Alternator - Installation
Before starting work, ensure the motorcycle is stabilised and adequately supported. This will help prevent it
from falling and causing injury to the operator or damage to the motorcycle.
