AC Output Check
1. See Figure 7-31. Test AC output.
a. Locate voltage regulator connector [46] under
sprocket cover. See 7.25 SPROCKET COVER WIRING.
Disconnect from alternator stator wiring.
b. Connect an AC voltmeter across stator sockets 1-2.
c. Run the engine at 2000 RPM. The AC output should
be 32-40 volts AC. (approximately 16-20 volts per
1000 RPM).
d. Repeat test across stator sockets 2-3 and 1-3.
2. Compare test results to specifications.
a. If the output is below specifications, charging problem
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 CURRENT
AND VOLTAGE OUTPUT TEST on page 7-28.
