I'm having some type of electrical problem with the TRIM/TILT on a 1997 Mercury 90hp ELPTO. I ran the boat on a Friday and the next morning no Trim/Tilt. it did hesitate the day before I lost it but then worked fine. I swapped out the relays for up & down thinking this could be the issue but it still doesnt work. I can here the relays clicking when I hit the switch from the Control box or cowling. Do you have an idea what I may be having problems with? I see on the schematic that there is a Harness Assembly that the relays plug into??? Could the harness go completely out? Any ideas on what I'm looking at would be great and I will order any parts needed to get it going. Thanks
