Charging the battery 

Connect battery and charger terminals positive to positive and negative to negative 

 

Warning: 

Battery releases explosive gas during charging. Ensure adequate ventilation. 

Note: 

1.

 

Standard charging current: 0.6 A for 5~10 hours. 

2.

 

Quick charging current: 6.0 A for 30 minutes. 

3.

 

Do not use quick charge except for emergency as battery life can be shortened. 

4.

 

Measure the battery voltage 30 minutes after battery is charged.  The battery 
voltage should be higher than 12.8 V. 

6.2.2

 

Rectifier 

Note: 

(1) Check if wire harness is undamaged before checking rectifier and end 
resistor. Check if rectifier connectors are secure. 
(2) Keep fingers away from tester probe.  The circuit resistance measurement can be 
invalidated with body resistance included.
