Need a suggestion for the trim wiring on my boat
I'd sure appreciate that.
I just figured that since they were clicking when they were sent a
signal.... they must be good. I have one spare that I slipped in, and that
responded the same.... so... I just figured  I suppose that it wouldn't be
too difficult to just purchase two brand new ones and see what that does.
I certainly would appreciate the wiring diagram though, above is my true
email address.
Thanks!

Hi,
Yes, it is an older boat... an 84 Welcraft 18' fisherman with a 83 140hp
johnson outboard. The trim switch indeed does have three wires, blue red
and
green all with white stripes.

As I was sitting here.... I got to thinking about the possibility that
there
may not be a good ground on the trim motor itself.... I got this
thought
after looking at the following diagram of a trim wiring circuit. Its
located
at the very bottom of the page... scroll down, the second image:

What do you think?
This diagram is for the older 3 wire system. I had assumed you had a 2
wire trim pump based on your posts, which uses the relays for current
reversing in addition to load handling. With the 2 wire system, each
lead takes a turn being "ground" depending on whether you are running
the pump "up" or "down".
So, what year is your outboard, and is it a 2 wire or 3 wire pump motor?

1983 is a 2 wire pump motor. They are all 3 wire trim switches. No
"ground" is necessary to the pump. How did you determine that the
relays are good? Your problem still points to the relays. I will
locate a wiring diagram and try to post it... or, is your email address
accurate?
