10.1.2 Charge Circuit Fail Alarm
The installer is responsible for a wiring which indicate a charge circuit failure alarm. In the
unlikely event of a charging circuit failure, indicated by the appropriate alarm, the electrical
bus bar will be fed automatically from the battery. Any non–essential electrical items should
be switched off.
The battery should be capable of providing sufficient power to run the ECU unit etc. for a
minimum of ½ hour. Reducing power will not significantly increase engine–running time.
