First time out this spring and the trim is stuck at full up/trailering position. Solenoid clicks when switched up, no sound and will not go down when switched down. I replaced the solenoid on advice of a friend, and problem is the same. I also checked and I do have 12V on blue with switch in up and 12V on green when switch is down. I added a little oil but did not want to add too much because shop manual says to add to top of fill with trim all the way down, but I can't get it to go down. Still no movement down and no clicking or other sound when switched down. Any ideas what to check next?<br /><br />This is a Glastron 1975 with a 140 Merc stern drive
