BATTERY VOLTAGE TOO LOW

• ACTIVATION: Voltage at the main microprocessor is less than 10 VDC.

• UNIT CONTROL: Shutdown and alarm

• 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 appropriate 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 Main

 

Microprocessor

a. Check connections at PCM-T1, T2 & T3. Verify that connections are not damaged or corroded.

b. Check voltage reading at 3MM-23 & 3MM-34. Must be above 11 VDC.

c. Check Unit Data voltage reading. Must be within 0.5 VDC of reading obtained at 3MM-23 & 3MM-34.

d. Check ground at 3MM-28 & 1MM-1. If ground is not good, check connectors and wiring between

terminals for damage, moisture or corrosion.
