I have several IC years from 2009 to 2012 with dt and max 7 engines with hyd brakes. Having issuses with the the ABS system, throwing code on message center saying ELEC FAULT and all the brake warning lights come on. I forget the code but it says to check the 1939 wiring all is good. Can't find any green ghost anywhere in the wiring, anybody else having this problem or heard about this problem.

Had a similar issue with the electrical fault and the fuse holders inside the battery box had wires that were breaking. You may check there.

^^^ Yup, and the connectors on that "clean" power cable from the batteries to the relays. Don't forget to check the relay plug as well. Any sign of melted plastic or dis-color wires, replace it.

I've heard that running the ground off the ABS module straight to battery ground is helpful on ABS electrical fault codes. That was mainly on 2006 models, but may be worth checking.
