There are two relays Jerry, one for up & one for down. They are merely
circuit completers between your switch(es) & your tilt/trim motor. Hyro
jackplates have two as well...been through a bunch of them puppies, they
don't like to get wet...

Wouldn't the relay on the motor control both switches? If I'm not
mistaken,
it probably controls the pump, not the switch.

A little help please....

My power trim switch on the throttle handle of my Yamaha 704 Remote
control has failed. It will not trim up. I checked the orginal
switch
with an ohm meter and it was reading 50 ohms when pressed in the "Up"
position and dead short when in the "down" position. I assumed that
the
switch..which was 5 years old had just become resistive. I ordered a
new
switch at a dealer....$60 worth and installed the new switch. I
installed
the new switch, tested it and the motor trimmed up fine. So..off to
the
lake! As soon as I'm in the water...I try to trim the motor up and it
isn't working...same problem! I haven't removed the new switch to
check
but I suspect that it has similar resistive characteristics.
The switch is a single pole double throw type switch. I measured
voltages
on the wires going to the switch and there is +12 volts on the
associated
leads to the up and down motion and 0 volts on the 3rd wire. This
indicates that the switch takes the voltage "low" to make the pump
turn
on
in the proper direction. I'm thinking that something is causing the
Up
switch contact to burn because its trying to pull to much current
through
the switch. Anybody had any experience with this problem?

thanks,
Bill Durham

Ps....the switch on the motor trims it up just fine..its just the
remote
that is failing.
