3.3.3. Coolant Temperature Gage 
NOTE: The pointer will typically indicate that the engine is operating in the 93-110°C or 
200-230°F range. If the indicator displays an abnormally high temperature (above 250°F 
or 121°C) then the engine is starting to overheat. If this occurs, shut the engine down and 
refer to the fault table in section 7.1. 
3.3.4. Volt Meter 
The two volt meters, pictured below, monitor the voltage of the primary and secondary 
engine battery. While the engine is running the normal voltage should read: 
•  13 to 14.5 Volts for a 12V system 
•  26 to 28 Volts for a 24V system
