Explanation
|
The voltage in the ECU battery located on the Kubota powerpack frame has fallen to below 11V. The ECU battery is only used to provide a stable voltage to the electronic components of the SMARTlift system while the Kubota powerpack is being started
|
Causes
|
- The system being left ON while the Kubota powerpack is not running
- Faulty ECU battery diode
- Faulty alternator
- Faulty charging connection to ECU battery
|
Operator Actions
|
- Start the Kubota powerpack to charge the ECU battery
- Check the connections to the ECU battery
- Request service
|
Service Tasks
|
- Check that the ECU battery is charging when the alternator is turning. The system voltage should rise to 14.2V and current will flow across the diode allowing the ECU battery to charge from the main battery
- Check the alternator voltage output if no charge current flowing.
