Evinrude tilt trim motor...more electrical than i thought?

[Larry Tate]

hey guys...i am a good mechanic on lots of stuff but i am not so hot with electrical. i was wondering if anyone could tell me if this relay would work for my used tilt trim unit for a 1979 evinrude 115 hp.

Larry, it depends as far as i know on if the motor is a 2 wire or 3 wire one. 2 wire i believe is for relay use, and 3 wire is for solenoid use ( i may be open to correction on this). I bought a 2nd hand t&t unit with no relay box last month and all i did was buy 2 relays and wire them up as per directions found in this forum and sealed them all in a box behind the transom and it works a treat and cost very little.

thanks for replying with some advice...its hard to get a reply on questions like this, i dont know why. can you tell me how to get to the forum where i can find out how to rig up my t&t unit? and also why do i need 2 relays? thanks

Larry,

I had a bit of trouble while researching kinda of the same query and ended up doing hrs of surfing to find what i needed to know.
From what i gather the relays are pretty much switches so one closes while the other one opens, thus letting the motor turn clock wise or anti c/w which then allows the trim cylinders to move up and down.

i used this diagram to wire the two relays

and it worked a treat.
I believe the relays were " single pole double throw" , what that is I haven't a clue but i asked for them and they worked.

also this may suit you too

Someone will surely be along with more good advice on wiring it up , but basically it goes.... motor - relay box- fuse panel & switch/s - battery.

thank you so much! this will work just fine...now that i know what a relay box is i might just rig one up on my own. totally waterproof of course, b ut maybe not $70. thanks again

or another diagram you may prefer ..it the same just a different concept ..surfed around in my head for 0. 2 seconds and there it was....Its the same circuit that is used on door locks in cars ..it has the advantage that when the relays are not activated the motor is shorted out which brings the RPM to zero real fast ( regenerative braking )
