VOLTAGE REGULATOR CONTROL
1. Connect multimeter. See Fig. 10 . Ensure charge indicator light goes out when engine is idling and with
increasing engine speed up to 3000 RPM. Apply load to battery by turning on headlights and noting
reading after 2 minutes.
2. Voltage reading should be 13-14.5 volts. If voltage is not to specification, replace voltage regulator. See
VOLTAGE REGULATOR
under REMOVAL & INSTALLATION. If regulator is okay, replace
generator. See GENERATOR under REMOVAL & INSTALLATION.
