Mercury Trim Gauge Wiring Diagram

The Mercury trim gauge wiring diagram is a valuable tool for any boat owner who wants to understand how their trim gauge works. This diagram shows the location of all of the wires and connectors on the trim gauge, as well as the function of each wire. By understanding this diagram, you can troubleshoot any problems with your trim gauge and make sure that it is working properly. The Mercury trim gauge wiring diagram is typically located in the engine compartment, near the trim gauge itself. It is a small, rectangular diagram that is printed on a piece of paper or plastic. The diagram is divided into two sections: the top section shows the location of the wires on the trim gauge, and the bottom section shows the function of each wire. The top section of the diagram is labeled with the letters A through F. These letters correspond to the terminals on the trim gauge. The terminals are located on the back of the trim gauge, and they are used to connect the trim gauge to the boat's electrical system. The bottom section of the diagram is labeled with the numbers 1 through 10. These numbers correspond to the wires on the trim gauge. The wires are color-coded, and the color of each wire is indicated on the diagram. The function of each wire is also indicated on the diagram. The following is a list of the wires and their functions: *

Wire 1:

This wire is the power wire. It provides power to the trim gauge. *

Wire 2:

This wire is the ground wire. It grounds the trim gauge to the boat's electrical system. *

Wire 3:

This wire is the signal wire. It sends a signal from the trim gauge to the boat's engine. *

Wire 4:

This wire is the return wire. It returns the signal from the engine to the trim gauge. *

Wire 5:

This wire is the speed sensor wire. It sends a signal from the speed sensor to the trim gauge. *

Wire 6:

This wire is the trim position sensor wire. It sends a signal from the trim position sensor to the trim gauge. *

Wire 7:

This wire is the trim angle sensor wire. It sends a signal from the trim angle sensor to the trim gauge. *

Wire 8:

This wire is the trim switch wire. It sends a signal from the trim switch to the trim gauge. *

Wire 9:

This wire is the overheat warning wire. It sends a signal from the overheat sensor to the trim gauge. *

Wire 10:

This wire is the low oil pressure warning wire. It sends a signal from the low oil pressure sensor to the trim gauge. By understanding the Mercury trim gauge wiring diagram, you can troubleshoot any problems with your trim gauge and make sure that it is working properly. If you are having problems with your trim gauge, it is always best to consult with a qualified marine technician.

Troubleshooting Tips

If you are having problems with your Mercury trim gauge, there are a few things you can check to troubleshoot the problem. *
