General Information
Starting Circuit
All Triumph models are equipped with an electric start system. This system consists of a starter relay, starter motor, starter
switch, sidestand switch, engine stop switch, cl utch switch and the sprag cl utch. The starter motor is connected to the
starter relay and the battery by heavy duty cables in order to su pply the large currents required by the motor to start the
engine. When the starter button is pressed the relay is energised, which then al lows cu rrent to the starter motor. The
starter motor will not operate unless the clutch lever is pulled in. Also, the starter will not operate if the sidestand is down,
unless the transmission is in neutra l. If the starter motor does not operate, the following basic checks must be carried out
before further diagnosis is performed:
Check the engine · stop switch is in the ' RU N' position.
•
Check the battery terminals a re clea n and tight.
Check the frame and engine earth connections a re clean, tig ht and free from corrosion.
Ensure the battery is fully charged and i n good condition.
•
Check that any fuse in the circuit is not blown and is of the correct rating.
•
Using the triumph d iagnostic tool, check the operation of the neutral switch or gear position sensor (if
fitted), sidestand and clutch switches.
Note:
•
On all new models from Daytona 675 onwards, which use a CAN connection between the
instruments and the ECM, the engine will not crank if the instruments are disconnected.
Rectify any defects as necessary.
