Testing Tilt and Trim

[bruoff]

Just brought my latest "baby" home. It's a 1986 50 hp Evinrude. The previous owner cut the tilt and trim cable about a foot from the motor. I want to check to see if the trim motor will work prior to a complete rewire. I have stripped the outer cable cover and exposed the three inner wires, (Black, Green, and Blue). I am assuming that the black wire is ground with the blue positive "up" and the green positive "down". Yes I have the factory manuals, but they give no color coded wiring diagrams. I just don't want to fry anything by arcing the wrong wires.

Black - Ground<br />Green - Down<br />Blue - Up<br /><br />Remember green grass and blue skies......<br />Attach black to a good battery ground.<br />Apply +12VDC to green wire, motor runs in down direction.<br />Apply +12VDC to blue wire, motor runs in up direction.<br /><br />Do you have the trim box that cable is supposed to run to?

No Box

Usually that trim box had a solenoid for up, but all current for down ran through the trim switch. If you're going to make your own box, I'd suggest two solenoids...

Thanks Tx, I'll check my parts book tomorrow. I can't find it on-line. I'm going to jump the black to blue, then green and see if I need to proceed.<br /><br /><br />Bob

Also remember a 2 position Mom. On-Off-mom.On will replace the expensive trim switch and it can be mounted right on the side mt control or the dash.....If you really need a box,then I may be able to produce one.<br /> Tim M
