My manual tilt assist unit broke, and I found a second hand power tilt/trim unit online. My engine is a BJ50 BELEDS. The PTT is shown in the picture . Blue wire, green wire, black (earth wire). Is that classed as a 3 wire? Before I try to connect to the engine, how do I test the motor directly from a battery. (i've seen it work before, but can't remember which wires to touch to the battery leads). If it goes O.K. then I'll get help to connect it up. I don't see any relays on the engine. I do see an unused 3-wire harness and connector (blue, green and white wires). Can you direct me? I may go to a mechanic if things sound complicated.

Touch blue to positive and green to negative to test for up.-----You will need the relays and wiring for it.---Do you have a switch on the control lever ?-----Wiring and 12 volts has proven to be an issue for some.----A shop will cost many beer tokens.

Depending on your ease of working electrical circuits......

see drawing for T&T with 3 wires ...typical hook-up picture a bit fuzzy but should be adequate for McGiver hook-up :)

in typical 2 wire T&T battery reversals on blue green will reverse up and down See 2 wire t&T) pic.


in a 3 wire T&T with ground common for blue or green....... try power to blue and ground then green and ground for up and down movements.

if it works then the fancy flip-flop arrangement typical of 2 wire systems need not be a concern if you simply drive the 2 seperate relays individually to power their respective color (blue and green with the battery supply. Ground being common for both functions.

Thanks for the replies. There is no switch on the control lever. I'm thinking I'll have to add one somewhere.

basically any single pole double throw switch should do if powering the low power needs of the transfer solenoid's coils . +12v on the central pin position

You can just buy the handle trim assembly online or used.

There's plenty out there or go to one on the dash. I've always gone with the throttle one though, safer and more effective.
