I just had the same problem. if your unit is showing code 32 (3 blinking pause 2 blinking) at the switch and you have plenty of battery power to the starter selonoid it is probably the relay. Cummins had to replace one on my unit. I was able to get it to work on occassion by tapping the relay selonoid in the electrical box (located outside under the DS window) that only worked for a few starts on my last trip until it failed entirely. It took cummins about 10 minutes to trace it and replace the relay causing the problem. Also check the fuse in that same area within the fuse block. there should be one for the generator.
If you call Entegra they will refer you to cummins. The good news it is a simple fix if you have the relay and it is a warranty item. I hope that helps you out.
