Bobcat 873 aux hydraulics not working

[Tannerc09]

I have a bobcat 873 series f that the aux hyd aren't working I've checked the coils and they seem to have the right ohms reading according to what I can find on the web I'm not getting any power to them while running the thumb stick on the joystick. But on the button the turns the aux hyd on it keeps turning the lock light on to the hyd cylinder light on about every second it changes back and forth I just put a new ahc controller/computer on it

THE MANUAL STATES AUX LIGHTS BLINK BACK AND FORTH= SHORT IN HANDLE ? NOW THE QUESTION TO ASK IS DO I NEED VARIBALE FLOW OR ON@OFF? OR GET BACK TO FACTORY SPEC.(RECCOMENDED)

Is there a way to test to see what handle is shorted out?
