Worn starter bushings result in? High Current Draw Worn starter brushes result in? Increased starter resistance Defective voltage regulator results in? A defective voltage regulator can cause overcharging and possible battery boil-over. Voltage regulators can be located in the alternator or in the engine control module depending on the application. What does a low battery electrolyte level indicate? Overcharging A loose alternator belt results in? Undercharging ...

1. Technician A only: A technician connects one lead of a DMM (digital multimeter)to the positive (+) terminal of a battery and the other meter lead to the "B" terminalof the starter solenoid and then cranks the engine. During cranking, the voltmeter displays a reading of 878 mV. Technician A says this reading indicates the positive battery cable has very high resistance. Technician B says this reading indicates that the starter armature is defective.Who is right? Technician A only ...
