5.3 Motor Control Testing
TPS Resistance testing - Set the circuit breaker and ignition to the “Off” position. Disconnect connector
1 (Black) from the MCU.
With a suitable Ohmmeter set to the 200Ω range test the following wire pairs on the main harness;
Black/White - Green/White ≈ 71.3Ω
Black/White - Red/White
≈ 150.8Ω
Green/White - Red/White ≈ 73.2Ω Connector 2 (White)
With the Battery and MCU correctly connected and the ignition set to the “On” position, test the
following wire pairs; (back-probe the MCU side of the connector)
Black - Red
≈ 4.67v
(HALL sensor power supply)
Black - Blue
≈ 0.05v to 4.65v
(Dependent on wheel rotation (approx 0.2°)
Black - Green
≈ 0.05v to 4.65v
(Dependent on wheel rotation (approx 0.2°)
Black - Yellow
≈ 0.05v to 4.65v
(Dependent on wheel rotation (approx 0.2°)
Black - Black/Blue
≈ 0.09v to 4.65v
(Dependent on wheel rotation.) Low to high voltage over
40°
rotation
of
the
wheel)
Black - White
≈0.25v
(Engine Temperature sensor - NTC type)
The Purple and Purple/Black wires are CANbus cables and connect to the Battery Management Unit
and the Speedometer display.
To test the MCU outputs to the motor it is necessary
to support the machine with the rear wheel raised,
side stand retracted and ignition set to “On”. Once
safely prepared, press the “Start” button and test the
following;
With a suitable voltmeter set to the 200v DC range;
Black to Red ≈66v (full battery)
With a suitable voltmeter set to the 200v AC range;
Black - Yellow (U terminal) ≈ up to 110v dependent on load (This can be higher when being driven)
Black - Green (V Terminal) ≈ up to 110v dependent on load (This can be higher when being driven)
Black - Blue (W Terminal) ≈ up to 110v dependent on load (This can be higher when being driven)
5.4 Battery and Circuit Breaker
The Talaria Sting is equipped with a high voltage lithium based battery which must not be
disassembled, altered or used in any way other than described in the user manual. It is
possible to test the battery voltage if required but caution should be used when handling
high voltage equipment.
The battery includes a Battery Management Unit
which will monitor the battery voltage. To check the
charge state, lift the battery cover and depress the
activation button and the unit will display current
charge.
