Exciter Coil - Kubota GL6000 Workshop Manual

GL6000, GL7000, GL9000, GL11000, WSM

(4) Exciter Coil

(5) Sub Coil (DC)
Grounding of Rotor Coil
1. Connect leads of a megohm meter between each lead and
exciter rotor laminations.
2. Reading should be more than 1 M at 500 V.
3. If continuous, replace the rotor assembly or contact service
station.
Checking Generator's Ball Bearing
1. Hold the bearing (1), and push and pull the outer race in all
directions to check for wear and roughness.
2. Turn the outer race to check rotation.
3. If there is any defect, replace it.
(1) Ball Bearing
Exciter Field Winding (Sub Coil)
1. Measure the coil resistance between each lead with a miliohm
meter.
2. If the resistance is not as specified, replace the stator or contact
service station.
(Refer to "5. WIRING DIAGRAM" (2-M8).)
Resistance Factory spec.
Grounding of Exciter Field Coil (Sub Coil)
1. Measure the insulation resistance between each lead and the
laminations with a megohm meter.
2. A reading should be more than 1 M at 500 V.
3. If continuous, replace the exciter coil assembly or contact service
station.
Sub Coil (DC)
1. Measure the coil resistance between each lead with a miliohm
meter.
2. If the resistance is not as specified, replace the stator or contact
service station.
