    Hello All!!! Hope everyone is having a Safe Productive Day. I’m trying to chase down an issue with my 2015 Freightliner Cascadia DD15 No Crank No Start when the key is turned. Only way I can start it is by jumping the solenoid. I was hoping someone on here would have the Starter Relay Wiring Schematics. I’d be most appreciative. Thanks in advance. Have a Great Day Everyone.

    Look in the fuse boxes on the firewall by steering shaft. I think I read there is a fuse for the starter in one of those.
    Good luck

    Try your local dealer. Mine will fax or email a copy of the circuit diagram by serial number.

    Thanks I appreciate it. My mechanic was able to trace the wire and found the issue of why it wasn’t starting. Needless to say the previous mechanic replaced my starter when he didn’t need to. So I’m def Salty about that but at least I’m up and running.
     
    BoxCarKidd and xsetra Thank this.
