Anyone have a spare FX/FXT Power Steering controller? part: 21175-0969

I bought a very used 2016 Mule Pro FX EPS (first ATV/UTV purchase)
On the test drive all lights including the EPS light came on when starting but did not stay lit when running.
Not knowing what I did not know I had no clue that the EPS was not working.

At this point i have opened the EPS controller and know it is dead (lots of corrosion under the black plastic cover).
The EPS motor looks ok but i don't know if it is functional so i am looking to buy a used but working control unit with the hope that it gets EPS going however it might move the point of failure down the line to an even more expensive item!

Anyone know of a way to test the EPS motor without a controller in the mix?
