I am currently swapping a power trim assembly from a 150 black max to a xr-2 150. I got the "new' assembly bolted on and bottom pin installed. Took 2 of 3 leads green/black and touched them to negative and positive battery posts reversed them and then did the same to the blue/black leads. Each time the motor/pump would run and the cylinder wont move from the retracted position. I did drain the assembly dry before I installed it and now it seems to not want to take fluid either. Anyone that can help point me in the right direction?
