AC Output Check

1. See Figure 1-25. Test AC output.
a. Disconnect voltage regulator connector from alternator
stator wiring.
b. Connect an AC voltmeter across stator connector
sockets 1 and 2.
c. Run the engine at 2000 RPM. The AC output should
be 40-56 volts AC (approximately 20-28 volts per
1000 RPM).

b. If output is good, charging problem might be faulty
voltage regulator. Replace as required.
3. Check the output again as previously described under
