Starting and Charging System-
Starting System5-23. WiringII. Starter assembly replacement (MR479Q, MR479QA, MR481QA)1. Remove starter assembly
(1) Disconnect starter connector.
(2) Remove nuts, disconnect starter cable.
(3) Remove 2 bolts and starter assembly.
2. Install starter assembly
Installation should be conducted in reversed direction of removal
Torque:
Bolt 37N.m
Wire harness 9. 8N.m (1) Check that connecting wire between positive pole of storage battery and starter must be firm and reliable,
outside shroud must be in good condition, so as to prevent generating electric spark and causing fire.
(2) Check whether wire is conducted, whether sheath is broken, if wiring harness is damaged, replace wiring
harness.Please Refer to "MK WIRING DIAGRAM"
