Features :
- Automotive battery load tester 100 Amp for car and motorcycle alternator 12V 6V tester
- Built in capabilities to test engine cranking ability, load, battery condition, starter motor draw and complete charging system diagnosis
- Comes equipped with 100amp rated copper gripping battery clamps and bottom selector switch for easy use
- Suitable for use with lead-acid batteries, including wet, gel, maintenance-free, EFB and AGM batteries
- Voltmeter scaled 1 to 16 volts
- 12-1/2" H x 6-1/2" W x 3-1/2" D (inch)
Application :
- Clamp the 2 clips of the tester to the positive and negative poles of battery,then the indicator lamp will light (the clip which lights is the battery's positive pole), voltmeter indicates that the battery's voltage is ghost voltage
- If the indicator lamp does’t light or the voltmetercan’t move, pls check if the clips connected well with the battery's 2 poles
- Twist the switch no more than 5 seconds(now the tester discharge 100A to the battery), and then the pointer of the voltmeter will move leftwards
- You can judge the battery's situation according to the position of the pointer
It often has 5 testing results:
- The pointer in green field, the battery has enough power
- The pointer in yellow field and stays stablely, the battery is in low power and needs to be charged
- The pointer falls fast to the left, the battery has no power at all
- The pointer turns to zero, the battery is outage of generation
- The pointer in red field, the battery may have defects
