I have determined that the relay switches are good.

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?

I've got a problem with the trim on my boat.

If I move the switch up or down, I can hear the relay switches click (I
believe that they are relay switches) but the motor does not move up or
down.

In the throttle, I have a green wire, blue wire, and a red wire. I tracked
that down to a box on the boat. The blue and green wire connect into
separate relay switches, with the same color wire going back out and to
the
trim motor. The red wire connects to a panel in the box.

My experiments to try to correct the problem:

If I place the main wires to the trim motor onto the battery, it makes the
motor trim work, green + blue - makes the motor go down, blue + green -
makes the motor go up.

With it all hooked back up.... if I connect the red wire from the trim
switch to the negative on the battery.... and then connect a wire from the
negative to a bare spot on the green wire AND another wire from the
negative
to a bare spot on the blue wire.... the trim switch makes the motor move
up
and down just like it is supposed to.... BUT the wires got HOT HOT HOT and
some of the insulation burned.... spark etc.... so I stopped, decided that
I
really should see of someone would offer a suggestion.

Again, if it is all hooked up properly (So I believe) I just hear the
relay
switches click but no movement on the motor. I REALLY would appreciate
some
assistance!
