The power supply to the ECM and the system
is drawn from the 24 volt or the 12 volt battery.
The power supply for the ECM has the following
components:
•
Battery
•
Disconnect switch
•
Key start switch
•
Fuses
•
Ground bolt
•
ECM connector
•
Machine interface connector
The Schematic for the ECM shows the main
components for a typical power supply circuit. Battery
voltage is normally connected to the ECM. The input
from the key start switch turns on the ECM.
The wiring harness can be bypassed for
troubleshooting purposes.
The display screen on the electronic service tool can
be used in order to check the voltage supply.
