NOTE: Prior to replacing the CDI unit to assure the CDI unit is defective, it is advisable to perform a CDI peak voltage test (see Ignition Coil in this section) and/or perform a continuity test of the wiring har- ness from the CDI connector to the CDI unit. Regulator/Rectifier The regulator/rectifier is located under the front rack and front fenders above the oil cooler. KC224 TESTING 1. Start engine and warm up to normal operating temperatures; then connect a multimeter to the bat- tery as follows. 2. Select the DC Voltage position; then connect the red tester lead to the positive battery post and the black tester lead to the negative battery post. 3. Start the engine and slowly increase RPM. The voltage should increase with the engine RPM to a maximum of 15.5 DC volts. KC223 NOTE: If voltage rises above 15.5 DC volts, the regulator is faulty or a battery connection is loose VOLTAGE 5 or corroded. Clean and tighten battery connec- tions or replace the regulator/rectifier. If voltage NOTE: Perform this test on the main harness side does not rise, check Voltage (Charging Coil - No of the connectors. Also, the ignition switch must Load) in this section. If charging coil voltage is be in the LIGHTS position. normal, replace the regulator/rectifier. 1. Set the meter selector to the DC Voltage position. 2.
