Have a 1981 Mer 150 I just bought. The tilt doesn't work and I have exhausted myself trying to get it working. I have read numerous posts and there seems to be a common thread going on here. When I hit the tilt/trim lever, all I get is a clicking from the solenoids. I have traced all the wires down and made sure all had good connections. I have tried jumping the solenoid to the best of my ability all I get is the same clicking. Any ideas on how I can check the solenoids or the pump? The fluid in the pump is clear and full... Please help. I have tried posting pics but the file is too big to upload. I will re-size and post pics later.. Thanks
