Battery Voltage Too Low
electrical
Description
Battery voltage at the main microprocessor is less than 10 VDC; engine and electric operation shut down and alarm, or alarm only if activated while starting unit.
Activation Conditions
Battery voltage at the main microprocessor is less than 10 VDC (except when the engine starter is engaged).
Unit Behavior
Engine and Electric Operation: Shutdown and alarm. Alarm only if activated while starting unit.
Reset Conditions
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.
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 8.10.11
