CHARGING SYSTEM
CHARGE/POWER COIL INSPECTION
CHARGE COIL
(*) Refer to page of base shop manual (iGX270UT2·
iGX390T2/UT2 Supplement Y).
Remove the control box (page 11-3*).
Measure the resistance between the terminals of the
charge coil.
Resistance:
QZX4 type (0.9 A): 5.1 – 7.7
QZA2, QZAV types (2.9 A): 0.4 – 0.8
QZN2 type (12 A): 0.22 – 0.34
Check for continuity between each terminal and engine
ground.
There should be no continuity.
• If the measured resistance is not within the range
specification or if any wire has continuity to engine
ground, replace the charge coil (page 8-4).
• If the resistance is good and the flywheel is OK,
replace the rectifier (QZX4, QZA2, QZAV types) or
regulator/rectifier (QZN2 type), and recheck.
POWER COIL

coil connector. (Engine wire harness side)
Resistance:
QZX4, QZA2, QZAV types: 2.9 – 4.5
QZN2 type: 2.8 – 4.4
Check for continuity between each terminal and engine
ground.
There should be no continuity.
• If the measured resistance is not within the range
specification or if any wire has continuity to engine
ground, replace the power coil (page 8-4).
• If the resistance is good and the flywheel is ok,
replace the ECM and recheck.
