Wiring<br />

In case of necessary repair of a cable connection, take special care that cable quality,<br />

isolation, crimping, strand end soldering of cable sockets as well as protective varnish isolation<br />

and/or connector locks meet the respective requirements.<br />

Tools for crimp connections to be found in tool catalog P/N Z001002/0 "Level 4".<br />

06.06.01 Electronic Engine Management System<br />

The STEYR Marine engine is equipped with an Electronic Management System (EMS) that<br />

performs the following:<br />

* controls engine functions to ensure maximum efficiency.<br />

* self-diagnostic to protect the engine from damage if operating parameter are exceeded.<br />

* stores diagnostic data of EMS server circuits for maintenance and service.<br />

Engine power is reduced if:<br />
