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.
