00016 Battery Voltage Too Low
• ACTIVATION: Battery voltage at the main microprocessor is less than 10 VDC (except when the engine
starter is engaged).
• UNIT CONTROL: Engine and Electric Operation: Shutdown and alarm. Alarm only if activated while
starting unit.
• RESET CONDITION: Auto reset after 15 minutes when the voltage at the main microprocessor is
between 11 and 14 VDC, or alarm may be manually reset using the display mounted keys 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 (refer to reset condition above). Operate the unit through the appro-
priate modes to see if any active alarm occurs. Continue with the steps below as necessary.
Corrective Actions:
1. Check for 00051 Alternator (Battery Charger) Not Charging
2. Check Battery Voltage
a. Inspect battery cable ends and posts. Must be clean and tight.
b. Test voltage at battery with unit off. Must be between 11-16 VDC.
c. Test voltage at battery with unit running. Must be between 12-16 VDC.
NOTE
Voltage with unit running should always be higher than voltage with unit off due to battery charging.
d. Perform load test on battery. Follow battery manufacturer’s procedure.
3. Check Connections to Power Module
a. Check connections at
BATT+, BATT-, and ALT+.
Verify that connections are not damaged or
corroded.
b.
Check Unit Data voltage reading. Must be within 0.5 VDC of reading obtained at ALT+.
If
voltages are out with unit running, check Battery Charger. Refer to
Section 8.9.11
