THIS IS A NEW CATERPILLAR 161-7153 HARNESS ASSEMBLY USED ON THE 3126B TRUCK ENGINE. THIS IS A SUPPLEMENTAL HARNESS THAT IS ADDED TO THE OEM HARNESS IF YOU EVER HAVE TO REPLACE THE ECM. IT APPEARS THAT THE OEM HARNESS DOES NOT HAVE FLYBACK DIODES TO SUPRESS ANY TRANSIENT VOLTAGE SPIKES. THIS CAN CREATE PROBLEMS IN THE IGNITION CIRCUIT OF THE ECM. IT IS POSSIBLE FOR THE ECM TO BECOME DAMAGED AND NOT ALLOW THE ENGINE TO SHUT OFF. THE 161-7153 IS INSTALLED DURING REPLACEMENT OF THE ECM TO PREVENT THIS FROM HAPPENING. COMPLETE INSTRUCTIONS ARE INCLUDED. (please look at our rules and privacy policy) |
