3. Start the engine and slowly increase RPM. The
voltage should increase with the engine RPM to a
maximum of 15.5 DC volts.
NOTE: If voltage rises above 15.5 DC volts, the
regulator is faulty or a battery connection is loose
or corroded. Clean and tighten battery connec-
tions or replace the regulator/rectifier. If voltage
does not rise, check Voltage (Charging Coil - No
Load) in this section. If charging coil voltage is
normal, replace the regulator/rectifier.
