SECTION 04 ELECTRICAL SUB-SECTION 06 (TESTING PROCEDURE)
Generator coil test (HI and LO)
This test is performed on the vehicle at cranking speedThe two generator coi ls are called high and low speed generator coilsThe checker indicates the output of these coils by switching HI and LO positions as followsHI: Output of high speed generator coil LO: Output of high and low speed generator coil Ana lysis of this test is diagnosed by its level
CONNECTION OF TEST WIRE HARNESS
a) Choose the right test wire ha rn ess according to the followingCODE NO IGNITION TYPE 4-4P ENGINE TYPE 464 TEST WIRE HARNESS
Control unit est
The COl checker inputs alternative current into the control unit instead of the generator coilThe output of the control unit will be indicated on the LED level indicatorAnalysis of this test is diagnosed by its level
277,377,503, 534
b) Connect the test wire harness to the checker aligning the arrow marks
Control unit diode test (for 4-5P ignition type, 277, 377, 503, 534 engine type)
The control unit includes the diode which controls the output of the generator coil according to the eng ine speed This checker can diagnose this diodeThe result will be indicated on the LED level ind icator
