Instrument Panel Assembly Controls and Indicators. The following items on the

instrument panel assembly allow the operator to monitor and control various electrical

system components.

1. The engine fan off switch is used to keep the engine fan from engaging during deep

water fording. The ENGINE FAN OFF indicator will illuminate on the lighted indicator

display when the engine fan off switch is positioned to on.

2. The ether start switch is used to start the engine when the outside temperature is 32
