Corrective Action
35
CHECK STARTER CIRCUIT
•
TRIGGER–ON: Engine speed fails to reach 50 RPM during 2 start attempts.
•
UNIT CONTROL:
Engine Operation: engine and unit shutdown and alarm.
Standby Operation: this alarm will not activate in standby Operation.
•
RESET CONDITION: Change unit to standby Operation 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, clear the
alarm(s). (See Note 1 page 7
−
2.) Operate the unit through the appropriate modes to see if any active alarm
occurs. Continue with the steps below as necessary.
1
Check That Engine Has Actually Started
Check that engine starts, runs for a
few seconds then shuts off.
If NO, continue with Step 2 below.
If YES, check wiring to RPM sensor for a broken
wire.
2
Check Starter Relay Circuit
a. Check operation of starter
solenoid relay.
Energize Circuit. (See Note 2 page 7
−
2.)
Relay contacts closed when SSR85 is grounded.
b. Check relay socket and terminals. No signs of discoloration from overheating.
No corrosion.
c. Check voltage to starter solenoid
relay.
Negative lead on 85, Positive lead on 86 = 12 VDC.
Negative lead on Gnd, Positive lead on 87 & 30 = 12
VDC.
d. Inspect wiring to starter solenoid
and starter motor. (See wiring
schematic Section 10.)
No physical damage to wiring or battery cable end.
No damage or corrosion in connections.
e. Check voltage to starter solenoid. Must be above 11.5 VDC.
f.
Check voltage to starter motor.
Must be above 10 VDC while cranking.
3
Check Fuel/Speed Actuator (FSA) & circuit
a. Check Run Relay LED
LED 28 must be ON.
b. Check for 12 VDC on the Run
Relay circuit
Must be 0 VDC
c. Check SPK20 for voltage
Must be 12 VDC
d. Check ENSCU terminals 13 & 15
for voltage
Must be 12 VDC
e. Check FSA plunger
Must be free to move
4
Check Starter
a. Inspect starter and wiring. (See
wiring schematic Section 10.)
No damage or corrosion.
Wiring and battery cable must be clean and tight
b. Check resistance of starter motor. Refer to Section 2.12 for correct electrical values.
c. Check amperage draw of starter. Refer to Section 2.12 for correct electrical values
.
5
Check Battery Voltage
a. Inspect battery cable ends and
posts.
Must be clean and tight.
No corrosion.
b. Test voltage at battery with unit
off.
Must be above 11 VDC.
c. Test specific gravity of battery.
Must be 1.225 or higher.
d. Perform load test on battery.
(Follow battery manufacturer’s procedure and
guidelines.)
6
Check For Correct Engine Oil
Check for correct oil viscosity (weight)
for conditions.
Refer to Section 2.8.
Must be correct for ambient conditions.
