Easy way to test the solenoids is to swap the tilt electrical plugs and put them on the side shift solenoids so when you operate side shift the tilt will work. If you put the side shift electrical plugs on the tilt solenoids its a quick easy way to test the output from the controller. Make sure to save a parameter file from the old controller to load up into the new controller after it is installed. Not saying this is a fix all for every case but just something to use as a guide.
