Start engine (TM 5-3805-248-10).
With the engine at normal operating conditions, run the engine at high idle.
Record the speed of the engine at high idle.
Add load on engine slowly until circuit tester light just comes on (minimum light output). This is the set point.
Record the engine speed.

The set point should be 1910-1930 RPM and high idle RPM recorded previously should be 2259-2369 RPM. If these are
in specification, no adjustment is needed. If the RPM recorded are out of specification in either case, repeat the follow-
ing adjustment steps until both are in specification.
