Ignition to starter is dead

[RodneyD]

2012 Berkshire 360fws 340 hp cummins. Ready to start a new year and went to the storage to flow some juices and engine would not start. Well I assumed I had bad batteries since they were 5 yrs old. Charged the house up so I could use my aux start button. Aux start button was dead, so I took my carry around charger and plugged into the starter batteries all night. Went back next morning and still wouldn't start. Aux start button still will not light up. Well I went down today and bought new batteries installed 2 heavy rascals 950 cca each. NADA!!!! I checked all fuses that had anything to do with the ignition, double checked the tranny in N checked fuses in the converter dept that said ignition. Nothing. The fuel pump will energize, the trans pad will light up and the dash will light up, the steps stopped at halfway and will not move from that position. I'm stumped. Has anyone had anything similar? Thanks
