Hi, i'm new in here.
I just bought an Clark TM12 forklift. This is my first forklift, so i need a users manual, service manual, and maybe a wirediagram (Having some troubles)

Well, the forklift drives well, except, It can't raise the forks, and the steering don't work either.

I dit find the contactors/relays? that starts the steeringunit, and the hydraulicunit.
If i give the coil power directly from a powersource, the respective device start. ie. the steeringmotor, or the hydraulic unit to lift and tilt the forks.
As an "emergency-repair" to use the forklift, i coupled a relay to the switch sitting near the levers to raise/lower/tilt, and it works great.
The steeringunit is started by a switch, coupled to a relay. So everything is working, just not the correct way.


It will be nice to find the failure, so everything works like the factory had in mind. So i have a bounch of questions
Why is there 4 switches to the steering? And what are they starting/stopping? I see two of the switches, triggers another relay (Not the one that starts the motor)
There is a box labeled Pulsomatic Mk. X, i don't know if that is a sort of controller?

What can i do to locate the failure? Bad connections, broken controller?

Thanks in advance. (And sorry, English ins't my native language)
