Front Cover Assembly Disassemble 

1、Disassemble all bolts. 

2、Insert flat head screwdriver between front 

cover and stator iron core and pry it adown to 

separate them. 

Caution： 

Do not insert screwdriver too deep so as to 

avoid damaging stator iron core. 

 

Pulley Disassemble 

Place pulley upwards and fix rotor on table 

vice, disassemble pulley. 

Caution： 

Don’t destroy rotor.

Stator/Regulator assembly disassemble 

1.Use electric iron    (180-250W) to un-weld stator, 

which should be finished in 4 seconds, preventing 

heat transfer to diode. 

2．When rectifier is removed from electric 

brush bracket, the two welding points on the 

rectifier should be un-welded. 

焊点 welding points 

Caution 

（1）When welding/un-welding welding points,        

please finish welding/un-welding as soon as 

possible instead of letting heat transferring 

from electric iron to diode. 

（2）Don’t pull diode cable forcibly. 

 

 

 

Reassemble Operation Tips 

Regulator assembly installation 

After installing regulator assembly, push 

electric brush inside and at the same time insert 

metal wire into the hole of rear cover to fix the 

electric brush.

wire 

Remarks 

Insert metal wire to fix electric brush and it 

will make rotor installation earlier.

2.Engine ECU Terminal 

Configuration 

 

Terminal configuration is as below: 

 

 

 

 

Engine ECU Terminal Check 

 

 

 

Terminal voltage check 

1.Connect mandrin(test cable:MB991223 or 

return pin) to the detect pin on voltmeter. 

2.Plus mandrin into the terminal of every ECU 

joint from harness side, and then measure the 

voltage of every terminal according to check 

table. 

Note：

 

（1）Measure the voltage when ECU 

terminal and harness joint are 

connected.

 

（2）Pull harness joint a little out from ECU 

terminal and let detect pin easily touch joint 

terminal, which is convenient to check. 

（3）You needn’t check it according to the 

sequence of check table. 

Caution: 

If plus terminal by mistake during check, which 

causes short, harness, sensor, ECU or other 

components may be destroyed. Please be very 

careful during check. 

3.If the voltage check result is different from 

standard value, please check related sensor, 

actuator and harness. If necessary, it should be 

repaired or replaced.

 

4.After repair or replace, check again with 

voltmeter to confirm if the failure is eliminated.
