Re: Over Crank Test CAT C15 Engine

Disconnecting the injector harness does not cause any damage and does not create any active or logged faults in ECM. 

Depending on your installation if you have a remote stop or E Stop it may be wired so that it does not also prevent cranking.

If so then this would be the most convenient way.

Over Crank Test CAT C15 Engine

Good morning everyone!


I was wondering if someone could let me know the proper procedure for doing the over crank test on  a CAT C15 Engine.


Some people have told me to unplug the injector harness and others have told me that I should just turn the fuel off.


I was wondering if anyone could tell me how to do this test the proper way so I dont do any damage to my equipement!
