Ok here's what happened. First trim would work then not. Then it would again. Well went to pull boat from lake and wouldn't raise at all. So removed trim cylinders and tied up and tied motor up also. Fluid was low. Well the down button worked and up didn't so I replaced solenoid. Still up button didn't work and didn't make noise. So pulled out the tester. No power from switch to solenoid. So removed throttle and switch worked fine. So cut the wire coming out to the solenoid and ran one from there to it to test. Now its working. But still cylinders not coming out. Looked like fluid might have air bubbles or foam. Im now thinking maybe an air lock up and needs bleed. But not positive. And to bleed could i crack a line and just run? Any ideas?
