9S0173 Alternator Circuit Breaker.
There have been reports of defective 9S0173 Alternator Circuit Breakers (1), that open and close intermittently. When the circuit breaker is open, battery charge stops. When it closes, a voltage surge through the system occurs.
When the battery charge falls below a predetermined level, or an excessive voltage surge occurs, the control system is automatically disconnected at the control box under the operators seat and all functions controlled by the joystick become inoperative.
When the alternator circuit breaker faults, check the fault codes displayed by the control box. Refer to the Special Instructions referenced above for details of the fault codes and remedial action required.
If the code indicates low battery voltage, check the charging system. Be sure that the 9S0173 Alternator Circuit Breaker is fully serviceable before including it in circuits to test other components.
