This is from Raymarine, testing the RRU. Maybe it will help
Rudder Reference Test
Here is the rudder reference test to confirm if the rudder reference is operating properly,
Red to Green: 5K Ohms (+/- 10%) Steady
Red to Blue: Variable no less than 1.5K no more than 3.5K as the wheel is spun hardover to hardover.
Blue to Green: Variable no less than 1.5K no more than 3.5K as the wheel is spun hardover to hardover.
The Red to Blue and Blue to Green may not go all the way to 1.5K or up to 3.5K, but whatever either is at midships, the deflection should be about equal to either direction(i.e. midships 2.5K if it goes up to 3.1K, it should go down to around 1.8)
Should the resistance measurements for the rudder reference transducer not be as specified above, then the rudder reference transducer should be replaced. Raymarine's part number for its rotary rudder is M81105. Please click here to view a FAQ addressing where one may purchase parts for Raymarine products.

That is resistance based and yes it will work.
