I am trying to give enough information without telling every troubleshooting step I am doing.In your typing you tend to leave out entire words so that makes following your conversations hard. But from what you have said like the part about the two wires on the o/p sensor and asking if it were just a ground makes me wonder if you have even looked at a wiring diagram? And if not how did you rewire the ones that were off? Next question is do you know how to follow a wiring diagram and actually convert the picture on the paper into what you see in the machine? If you do not follow the troubleshooting procedures to the letter from start to finish you will never find the problem. You absolutly cannot skip any part of the trouble tree! Personally I have no experience with this machine, but some of the people answering you have a LOT of experience with them and you are not paying attention to what they are telling you. You are jumping around making your own "assumptions" in between them trying to give you solutions. You will find out real fast that this is the fastest way to lose very good help!
original problem was it would crank/start then shut off almost immediately.From what I am reading from the comments maybe I was not holding the start switch long enough to build oil pressure. While doing troubleshooting for that problem I found a total of 4 wires disconnected on the TB5. The numbers on the wires correlated with slots 1 and 2 on the TB5 according to the schematic. After attaching the wires to the correlating spots I would turn the start switch and it would not crank and the LOP light came on. Followed the troubleshooting for that and it advised to clean the sensor. Cleaned the sensor off and now I have no LOP light but still no crank. When testing the oil pressure sensor the troubleshooting says it should have “x” ohms but no matter what I tested I could only get it to read overload or 0 ohms. According to the comment above I can jump it to eliminate the sensor.
Engine starts and runs fine using the dead crank switch.
I am very familiar with mechanic diesel engines but not very familiar with military equipment and the electrical side.
