16. BATTERY/CHARGING SYSTEM DINK50/ 125 (DINK 50) REGULATOR/RECTIFIER INSPECTION Remove the front cover. Disconnect the regulator/rectifier wire coupler and remove the nut to remove the regulator/rectifier. Nut Regulator/Rectifier Measure the resistances between the terminals. Replace the regulator/rectifier if the readings are not within the specifications in the table below. · Due to the semiconductor in circuit, it is necessary to use a specified tester for accurate testing. Use of an improper tester in an improper range may give false readings.
