Circuit Descriptions

Engine Starter Control

Holding the key switch in the start position supplies a 36 volt “input request” to the main machine controller

to engage the engine starter. In turn the main machine controller sends a 12 volt output to the starter relay

winding. The other side of the winding connects to the ECU. The ECU must connect the circuit to battery

negative to energize the starter relay. If the engine is already running, the ECU will prevent the starter

relay from operating.
