On 2 ocassions now ive seen Yamahas that wont trim down , on one ocassion i started the engine and then the motor trimmed down , any ideas ?
 
Yeah, it sounds as if the electrical side of the trim and tilt is faulty. To check it simply take the two wires from the trim motor and ground one side and put the other side on positive. It should go up or down, depending on the color of the wire on the postive side. Blue=up Green=down. You have solenoids that provide ground or positive, depending on what selection you make with the switch, which should work with the key off.
