EPS not working

So, I got my Grizzly back today from a friend who did a rebuild on the bottom end which was toast after the diff plate broke and ate the case and gears. Proballer helped me out with a used motor for cases and a few gears. I put a new chain, oil pump, and Weller racing diff plate in it and replaced the gears that were damaged. All this was after the wet clutch, drum, and one way bearing were replaced because of excessive heat. I also added slugs and a brand new belt.

All of the above damage, along with a toasted stator harness and the EPS quitting was done by someone else when I let a friend of a friend ride it. It came back in the damaged shape not running. It had no issues with anything prior to loaning it out.

So now everything is repaired except the EPS is still not working and the light is on. If the bike threw any codes when it went down, I do not know. It does not show any now. My question is…Would the stator issue have caused any issue with the EPS (ie low voltage or possible relay damage) or is it more likely that the two are unrelated? Best place to start diagnosing the EPS?? Seemed very odd that it all went bad at the exact same time. The steering is not locked up and is drivable but I want to get it all back working, especially if it is just a matter of clearing or resetting the codes. Any suggestions would be greatly appreciated
