Starting Circuit Instructions

The Starting Circuit instructions provide detailed guidance on initiating the excavator’s engine. Follow these steps:

1. When the key switch is set to START, the current connects terminal B to terminals M and ST.
2. This energizes the battery relay through the key switch ON cut relay, routing the current from the battery to the starter.
3. The current flows to fuse #17, providing a signal to various system controllers indicating the switch position.
4. Upon receiving this signal, the ECM turns on its main relay, powering the ECM and enabling engine starting conditions.
5. The relay in the starter is engaged, allowing the starter motor to operate and start the engine.
