Voltage regulating rectifi er inspection
Test and Judgment Method of Charging Voltage on Whole Vehicle
Test conditions and methods Output voltage
1. Connect the product according to the normal loading
state, after the vehicle started, the speed will remain
above 2000rpm;
2. Bring a fully charged battery;
3. Use a multimeter to test the voltage at the output
terminal of the regulator
Output voltage:14.0-15.0V
Qualifi ed; otherwise unqualifi ed
