GENERATOR COIL RESISTANCE
• Disconnect the generator coupler 1 .
Measure the resistance between the B/R lead wire and ground
using the multi-circuit tester. If the resistance is not within the
specified value, replace the generator coil with a new one.

Generator coil resistance:
GENERATOR NO-LOAD PERFORMANCE
• Disconnect the regulator/rectifier coupler 1 .
• Start the engine and keep it running at 5 000 r/min.
Measure the voltage between the B/R wire of regulator/rectifier
coupler and ground using the multi-circuit tester.
If the tester reads under the specified value, replace the genera-
tor with a new one.
