I brought my boat home from the lake and parked it. I let the motor down to do some work on it. Now it won't raise or lower. I checked the power to the relays and they are getting power. I checked the wires coming out for power when I push the tilt/trim button and there was power. I don't hear any kind of noise when I push the tilt/trim button for up or down. I have a Seloc book and it talks about a sending unit. Anybody know where that is located. I also seen some posts about their being a selinoid for the tilt motor but I don't see that either. Thanks in advance for any help.
