15. BATTERY/CHARGING SYSTEM/ A.C. GENERATOR ATV 50 Resister B RESISTOR INSPECTION Measure the resistance between the resistor B pink wire and ground. Measure the resistance between the resistor A green/black wire and ground. Resistances: Resistor A: MX'ER 50: 9.29.8 MXU 50 REVERSE/MXU 50: 11.812.5 Resistor B: MX'ER: 5.66.2 Resister A Faulty resistor is the cause of faulty operation of the auto bystarter. Coupler Nut REGULATOR/RECTIFIER INSPECTION (MX'ER 50) Disconnect the regulator/rectifier wire coupler and remove the nut to remove the 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 Regulator/Rectifier accurate testing. Use of an improper tester in an improper range may give false readings.
