CHARGE/POWER COIL INSPECTION
POWER COIL
(*) Refer to page of base shop manual (GX240/GX270/
GX340/390UT2, P/N 61Z5F00E3).
Remove the air cleaner element
Disconnect the power coil connector.
Check for continuity between the terminals of power coil
connector. (Engine wire harness side)
Resistance: 2.9 – 4.5
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
• If the resistance is good and the flywheel is ok,
replace the ECM and recheck.
CHARGE COIL
Remove the control box
Measure the resistance between the terminals of the
charge coil.
Resistance: 5.1 – 7.7
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
• If the resistance is good and the flywheel is ok,
replace the rectifier and recheck.
