Voltage regulating rectifi er inspection
Test and Judgment Method of Charging Voltage on Whole Vehicle
Test conditions and methods
Connect the product according to the normal loading
state, after the vehicle started, the speed will remain
above 2000rpm
Connect a fully charged battery
Use a multimeter to test the voltage at the output terminal
of the regulator
