Section 06 ELECTRICAL Subsection 06 (TESTING PROCEDURE)
INSPECTION OF AC CIRCUIT INSULATION
Fan Cooled Electric Start Models If AC circuit is not insulated from frame, headlamp beam will weaken
300 and 360 Models
LOW INTENSITY HIGH INTENSITY YELLOWBLACK wire ORANGEVIOLET wire YELLOWBLACK wire ORANGE wire 10.9 to 13.4 ohms 5.5 to 6.8 ohms
INSPECTION
Disconnect regulatorrectifierConnect one digital ohmmeter probe (needle ohmmeter will not offer enough precision) to frame and other probe to YELLOW wire (2-MO)Measured resistance must be infiniteIf such is not the case, it means there is connection between AC circuit and frameDisconnect one accessory at the time to identify the faulty circuit
When measuring resistance at terminals the actual value will be half the measurement in tableThe reason for that is the elements are connected in parallelTherefore the total resistance is half the resistance of one element
