AC Output Check
1. See Figure 7-51. Test AC output.
a. Locate voltage regulator connector [46] behind left
footrest support. Disconnect from alternator stator
wiring.
b. Connect an AC voltmeter across both stator sockets.
c. Run the engine at 2000 RPM. The AC output should
be 38-52 volts AC.
2. Compare test results to specifications.
a. If the output is below specifications, charging prob-
lem could be a faulty rotor or stator.
b. If output is good, charging problem might be faulty
regulator/rectifier. Replace as required.
3. Check the output again as described under
Voltage Output Test.
