STARTER SYSTEM

B. Red ashing of the battery indicator LED indicates that battery voltage is too low and needs to be

charged.

C. Green ashing of the battery indicator LED indicates that a short circuit occurs in the electric starter.

Check the electric motor and the motor drive lines as below:

Open the corrugated pipe and disconnect the male and female terminals of the motor drive lines (blue)

(Fig. 82). Press the start button and check if the LED ashes green. LED does not ash - the short

circuit occurs in the electric motor or the motor drive lines of the engine. LED ashes green - the short

circuit occurs in the motor drive lines of the handle.

D. Alternate red and green ashing of the battery indicator LED indicates that an overcurrent occurs in

the electric starter part. Check if the engine is stuck and cannot be rotated smoothly. Check if there

is any foreign matter, such as metal, magnetized on the ywheel.

E. If the battery indicator LED is continuously on, check that if an open circuit occurs from the PCB

output to the motor connecting line.

When pressing the start button and the LED is continuously on, test the voltage output in the motor

drive lines using the DC voltage stall of multi-meter (Fig. 83).

If there is voltage output, the possible causes are as below:

1). The electric motor has broken down;

2). The motor drive lines of the engine have detached from their welding position to the electric

motor;

3). There is loose or failed contact in the connection from the motor drive lines of the engine to the

male and female terminals in the corrugated pipe buckle.

If there is no voltage output, the possible causes are as below:

1). The motor drive lines of the handle have detached from their welding position to the PCB;

2). There is loose or failed contact in the connection from the motor drive lines of the handle to the

male and female terminals in the corrugated pipe buckle.
