Tilt Trim issue

[DYI]

Good Day all!


I am working on a 1979 Sea Ray SRV 190, from what I can tell it has been re-powered with a 1977 ish Mercruiser 888 (302 2bbl) 188 HP.


At one point I had the out drive all the way down, and could't power it up,(out). After a trip to the friendly Mercruiser dealer I am now able to power up but not all the way down. The trim sensors are there, but not connected to anything, (both black with male bullet connectors). I followed them throught the bellows.


Am I to assume that the trim is defaulting to lock out before the outdrive gets all the way down? There are 3 buttons on the trim control is one an override for down, or just up?


Does anybody have a wiring diagram for the trim on this old boat. FYI most diagram i have seen have two solenids, my setup only has one. The control is dash mounted with 3 buttons.
