ING. 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 prob-
