function is corrected.

Proper output is approximately 13.5 Volts with
engine running at governed speed.
4. Observe water temperature gage indication of
engine coolant temperature. Proper operating tem-
perature is approximately 160 to 185°F. for Detroit
Diesel engines and 175 to 210°F. for Caterpillar
engines.
5. Observe air pressure gage indication of brake sys-
tem pressure (furnished only on units equipped for
