Resettable circuit breaker F13 B for Eaton Shift Tower issues

Check battery box for fuse to transmission if it is bad truck wont start

 

Check all the wires you have a short see if they are rubbing on something and see if you can pull shift pad out and see wires if rubbed on anything if the fuse goes that fast its a dead short should not be that hard to find move wires away from walls tell it don't pop then look for short

 

Prostar and 9400I are two different trucks. I am guessing you have a 9400I. International makes wiring changes all the time, so it is very important that you know the build date of the truck. This is located in the drivers door pillar, it is white sticker with black ink. This sticker has the vehicle identification number on it. The date of manufacture will be printed on it too. I have looked through a couple of wire diagrams and found that possible 10 amp breaker is the main ignition feed to the shift selector and the gear display in the switch panel. Either the wire itself has rubbed through somewhere in the dash, or the shift selector, or the display has an internal short. Since the breaker is popping right away, you can test what is causing the short. Open up the dash so you can disconnect the shifter and the gear display one at a time. Each time you disconnect something, reset the breaker and turn the key on. If the breaker does not pop after something got disconnected, then that component is the problem. If you have both the shifter and the display disconnected and the breaker is still popping, then the power wire between the breaker and the components is rubbed through on something metal somewhere in the dash.
