Hello y’all
My first post but I’m a little lost now at what’s next
So I’m the sole mechanic for an excavation company and have 22yrs worth of debt for my box (that’s worth 10of my truck) lol
Our D4G had a mishap
Soooo needless to say I went out one chilly morning started it to let it warm up before I brought into the shop for service track adjustments etc etc it warmed up I went out went to throttle up to bring it in and POOF engine went full tilt no control smoke and smell of burning wires ugh lucky me.
so anyways after tearing into it I figure out the last one that was in it forgot the p-clamps for the throttle cables and left it hanging ontop of the main battery cable and engine management harness, and I was the lucky one who finally hit copper, I now have the following.
New electrical from nose to engine to ecu
New speed sensor
New throttle cables (both melted)
New start relay
New engine shutdown timer
New cab harness to dash
New starting solenoid and switches and brakers
Half a dozen sensors on engine
Here is where I got.
i can get it running under control from the cab without the power wire to the solenoid, but it’ll start but not shut off with the key and with it on it won’t start no fuel ugh now I’m checking for faults after deep research into that engine shutdown timer as I wanted to bypass it too and found that that timer works two fold.
One. It sends and keeps power for a few seconds to the fuel shut down solenoid to ensure engine shutdown
Two. It also PREVENTS starting when ecu discovers a fault that will cause damage to the machine or more then likely to.
I am leaning to a secondary short under cab on hydraulic system and telling the ecu to not start. I’ve ohmed out the entire engine side of the new harness and ecu and tested everything else
