Re: Trim up switch no response how do I check it?
Blue,<br /><br />I do not know what kind of engine you are working on.<br /><br />However, most trim switches employ three wires. One common, one up, one for down.<br /><br />It's simple to test. Since you have motor activation in one direction, you can assume your common (hot) wire is OK.<br /><br />That leaves one of the other two circuits dead.<br /><br />Get a test light and ground the test light clamp lead. Touch the testlight probe end to either of the other two wire terminals while activating the switch. That will tell you which circuit is dead.<br /><br />Let us know.
