Ttilt trim issue

I have a 1986 60 horse Evinrude that is in excellent shape. The tilt trim motor and hydraulics are fine because I can make the motor go up and down by applying 12 volts directly to the blue or green wire. I have tested the solenoids with an ohm meter per the manual and they both check out. I have looked inside the remote control box and everything seems normal. Is it possible to switch on the handle of the remote control lever has gone bad? If it went bad wouldn't it just fail in only an up or down direction? Advice has to where to go next is greatly appreciated!
 
There is a wiring harness coming from the bottom of the remote control handle that has 3 wires going in and out of a connector. Wires are red/white, blue/white and green/white, picture attached. I presume these are the trim control wires, correct? Can I just jump the red wire to the green or blue wire to test the trim down or up respectively?

Also I attached a pic of a red wire that plugs into the back of the remote control. It is not hooked up to anything presently. Is this wire for a tach or something else?

Thanks for your help!

The red wire tests positive for 12V but connecting it to the blue or green terminal does not run the T/T motor so the problem is not in the switch. What else could be the culprit? Can the solenoids pass all the continuity tests the manual describes but still be bad? When I got the motor the tilt/trim worked fine but then stopped working some time ago. This has not been a huge problem because I'm running a jet pump on it so I don't need to use the tilt/trim frequently I am concerned I may want to raise the motor when I am on the river if the pump needs attention.
 
Find the connector that goes to the trim motor.-----It has a blue and a green wire.----Just 2 wires.-----Put + to blue and - to green.-----Motor should trim UP.-----Now connect + to green and - to blue.----Motor should trim down.

Racer: As mentioned in my original post I do that whenever I really need to raise the motor which is not often as it is an outboard jet setup that performs great in the full down position.

I am attaching another photo showing black and white wires and associated connector which are located near the remote control that are part of the T/T circuit. The black and white wires are not connected to anything. I am guessing the black wire should be attached to ground, correct? What about the white wire? Does it need to be connected to 12V? If the white wire should go to 12v is it ok to be attached to unswitched 12V (full time hot) or should it be only hot when the key is on?

Thanks for everyone's help!
 
The motor operates with the red , blue and green wires.----On that black plug in.-------The other wires are for an optional trim gauge perhaps.------Do not hook up any wires with the ---" lets see what happens "---- approach.----Smoke gets expensive.
 
After more testing I confirmed the switch is bad. An OE switch with harness is $245...I bought a SPDT momentary rocker switch for $10 I will mount on the control panel. Thanks to all that provided inputs!
 
I installed a new switch and it still did not work! After more investigation it turns out the problem was a bad three-way connector located near the remote control. The faulty connector was intermittent in nature making for a puzzling diagnosis but the connector is in the garbage (soldered the wires together) and the tilt and trim works perfectly with the new switch!
