Jody Scott Posted 21 hours ago Share Posted 21 hours ago Hello, my 2002 CH613 is cutting out and dies while i am driving. I can cycle the key and it will start back up but not an ideal situation in traffic.

Joey Mack Posted 21 hours ago Share Posted 21 hours ago If it is a total electric cut out. I would look at wiring issues, or even hot relays. They are in the panel on the right in the cab fuse panel.. I should have mentioned the ground connections...

Jody Scott Posted 21 hours ago Author Share Posted 21 hours ago I still I have power to the cab, the a/c and lights are operational but the RPM gauge goes straight to zero.

Jody Scott Posted 21 hours ago Author Share Posted 21 hours ago I have replaced the transmission the other day and was thinking maybe the RPM sensor on the flywheel housing maybe?

Let us know what you find ! The flywheel sensor is a good first step!

Joey Mack Posted 5 hours ago Share Posted 5 hours ago I typically post the 9-2 fault code bulletin for this because it is about checking the grounds. 9-2 code.pdf 1 Quote Link to comment https://www.bigmacktrucks.com/topic/76619-my-2002-mack-ch613-engine-is-skipping-and-shutting-off-while-i-am-driving/#findComment-595401 Share on other sites More sharing options...
Jody Scott Posted 2 hours ago Author Share Posted 2 hours ago I am getting a 2-4 code and that doesn’t make any sense.

Jody Scott Posted 2 hours ago Author Share Posted 2 hours ago My stubborn mind is fighting the ground idea because i live in a dry climate and i did not mess with any grounds/ wires accept the three wire connections on the transmission. I did clean the connections on all the terminals on the batteries and still this bugger is still kicking my tail. The truck ran fine until i messed with it.

Jody Scott Posted 2 hours ago Author Share Posted 2 hours ago I ordered and will replace the speed sensor and the flywheel sensor tomorrow and see what that gets me.
