1994 yamaha saltwater II. Just put on a new electric motor for the hyd motor trim?.and nothing? if I hook up the green to - and the blue to + straight off the battery the unit will go down? as far as the wiring hooked to the motor?nothing the voltmeter gives me 12.62 touching the red to the blue or green and the black to any ground. If I pull either the green or blue off the motor terminals the voltmeter will not register any volts. Pushing the up/down button on the side of the motor does make a sound when depressed either way and a drop in volts to like 12.4 on the blue or green. The other two black wires are hooked up the whole. What am I doing wrong here.
