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.

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?

Rob




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?

Rob

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!

The relays will continue to "click" long after the contacts have gone
bad. Try your third relay in place of the other one.

Diagram has been sent to you.
