LOW FUEL LEVEL WARNING
Note:
This is an optional alarm which will not occur unless a fuel level sensor is present and configured ON.
•
TRIGGER ON: Fuel level is 15% or less for more than 30 seconds.
•
UNIT CONTROL: Engine operation: Alarm only. Standby operation: Will not activate in standby.
•
RESET CONDITION: Auto reset when the fuel level is above 17% for more than 30 seconds, or alarm
may be manually reset via keypad or by turning the unit off, then back on again.
NOTE: Follow the steps below until a problem is found. Once a repair or correction has been made, the active alarm
should clear itself (see reset condition above). Operate the unit through the appropriate modes to see if any active
alarm occurs. Continue with the steps below as necessary.
1.
Check For Low Fuel Level
a. Check fuel level in the fuel tank
Add fuel as needed to the fuel tank.
2.
Check Fuel Level Sensor
a. Inspect fuel level sensor& connector
pins & terminals
No physical damage to switch.
No damaged or corroded pins in plug.
b. Check fuel level sensor operation
Energize circuit. See Note 2.
c. Check for voltage at harness plug
between pins for BLACK (SP24)
negative and RED (SPK5) positive
wires
Voltage should be approximately12VDC.
d. Check for voltage at harness plug
between pins for BLACK (SP24)
negative and WHITE (1MP26)
Voltage should be greater than 0 VDC and less than 5
VDC, unless the probe is completely dry.
e. Check continuity of the wire from the
harness plug, pin C to the microproces-
sor plug 1MP26
Place Start--Run/Off Switch in OFF position prior to
checking for continuity. Must be less than 10 ohms.
3.
Check Fuel Level Sensor Calibration
a. Check fuel level sensor calibration
See Section (8.5.1) for sensor calibration procedure.
4.
Check Circuits With Test (Substitute) Sensor
a. Substitute known good sensor and
clear alarm. Start unit and run for 30
seconds.
b. Check to see if alarm re-occurs.
Alarm should not come on. (Install new sensor if
necessary)
