Control Panel Indicators (RB-S)
C.2.a.
Overheating
Indicator
If the engine overheats, the RED indicator light will come on, engine speed
will be gradually reduced to approximately 1800 RPM and the engine will
stop after 20 seconds. The overheating indicator is activated via the engine
control module (ECM) by two overheat sensors mounted on the engine.
The Honda 225-HP engines require approximately 12 PSI water pressure
with a minimum water pressure of 5 PSI to maintain adequate engine
cooling and prevent engine damage.
C.2.b. Oil
Pressure Indicator
If oil pressure becomes low, less than 23 PSI at 1800 RPM, the GREEN oil
pressure light will go off. If at cruising speed, the ECM will gradually
decrease engine speed. Stop the engine and check and service the oil level.
Restart the engine. The GREEN indicator light should come on within 30
seconds and throttle operation should be normal. If the engine protection
system remains activated, oil indicator light off, engine RPM will not
increase with throttle movement. Stop the engine and repair as required.
C.2.c. Alternator
Indicator
The RED indicator light will come on if there is a malfunction in the
charging system. Each engine alternator is rated at 12 VDC, 60 amp at
2300 RPM, and produces 48 amps of power at 1000 RPM. The alternators
are belt driven by the engines and protected by a 150-amp fuse installed in
the fuse case mounted on the engine.
