Re: trim and tilt
Checking with a test light will not tell you the relay is good. The internal contacts of the relay may be pitted allowing only a reduced contact surface. There may be enough current getting through to power the light, but not enough to power the pump. Better to bypass the relay by jumping across it with a cable. That will better allow you to determine if the problem is with the motor or the relay/connections. Make sure all connections (including ground connections) are clean and tight.
