bdi displays voltage continuosly over time even though the machine is sitting idle, will drop signifcantly, battery pack at 25 volts and bdi showing 40%

A possible cause of the BDI on a Yale MPB045VG displaying continuous voltage over time while the machine is idle, with the battery pack at 25 volts and BDI showing 40%, could be that the Keyswitch Input (KSI) is still on. The BDI algorithm continuously calculates battery state-of-charge whenever KSI is on, even if the machine is idle. This can result in the BDI continuing to show changes in voltage or state-of-charge.

Lights are flashing but not charging

The lights may be flashing on the Yale MPB045VG and not charging due to a detection error or abnormal shutdown. According to the LED status indicators:

- If the red DET (Detection Error) LED is illuminated continuously, the battery is either not connected to the charger or the battery voltage is less than 2V.
- If the red SDN (Abnormal Shutdown) LED is flashing, an abnormal shutdown has occurred.

These conditions prevent the charger from starting the charging cycle.

The battery for the Yale MPB045VG may not be charging due to several possible reasons:

1. Battery Damage or Leakage: Check the battery case for damage or leakage. If damaged, it must be repaired.

2. Worn or Aged Cables: Inspect for aged or damaged wires or cables that may prevent charging.

3. Incorrect Charger or Charging Procedure: Use only chargers approved by the battery manufacturer and follow the specified charging procedures.

4. Poor Ventilation or Obstructed Vent Caps: Ensure proper ventilation during charging and keep vent caps clear.

5. Low Electrolyte Level: Make sure the battery plates are covered with electrolyte before charging.

6. Overheated Electrolyte: Do not charge if the electrolyte temperature exceeds 49°C (120°F).

7. Battery Left Discharged: Avoid leaving the battery completely discharged, as it can prevent proper charging.

8. Welded Contactor Tips: If the truck was operated with a low battery, check for welded contactor tips.

Any of these issues can prevent the battery from charging properly.

Will not turn on or charge.

The Yale MPB045VG may not turn on or charge due to several possible reasons:

1. Battery Issues: Ensure the battery is rated at 24V and is properly connected to the truck. If the battery voltage is too high or too low, the truck may not operate.

2. Controller Wiring Fault: Measure the voltage between the traction controller B(+) terminal and B(-). If the precharge voltage is not the same as the battery voltage, inspect the B(+) cable for damage or loose connections.

3. Faulty Controller: If no wiring faults are found and the issue persists, the controller may be faulty and require replacement.

4. CANbus Communication Issues: If CANbus communication is interrupted, check for open circuits, missing or damaged termination resistors, or internal control module failures.

5. Capacitor Discharge Needed: If an error code is present, try disconnecting the battery, discharging the capacitor, reconnecting the battery, and restarting the vehicle.

Following these steps can help diagnose and resolve the issue preventing the truck from turning on or charging.
