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.
