Volvo Penta is a trusted brand that manufactures high-quality marine engines and systems. One of their products is the trim sender, which is essential for controlling the trim angle of a boat. However, some boat owners may encounter issues with the trim sender wiring, which can cause problems with the trim function. In this article, we will discuss the wiring diagram for the Volvo Penta trim sender and provide solutions to common issues.
What is a trim sender?
A trim sender is a device that measures the position of the boat’s outdrive or sterndrive, which is used to control the trim angle. It sends the position information to the trim gauge, which then displays the angle on the dashboard. The trim angle affects the boat’s performance, speed, and fuel consumption, so it is essential to have a reliable trim sender.
How does the Volvo Penta trim sender work?
The Volvo Penta trim sender consists of two parts: the sending unit and the gauge. The sending unit is installed on the outdrive or sterndrive, while the gauge is mounted on the boat’s dashboard. The sending unit has a variable resistor that changes its resistance based on the position of the outdrive or sterndrive. The gauge reads the resistance and displays the trim angle on a scale.
What are the common issues with the Volvo Penta trim sender wiring?
One of the most common issues with the Volvo Penta trim sender is wiring problems. The wires can become loose, corroded, or damaged, which can cause the gauge to malfunction or display incorrect trim angles. Additionally, incorrect wiring connections can damage the sending unit or the gauge.
Wiring diagram for Volvo Penta trim sender
Before attempting to fix or replace any wires, it is crucial to have a wiring diagram for the Volvo Penta trim sender. Here is the wiring diagram for the trim sender:
| Wire color | Function |
|---|---|
| Green/white stripe | Signal from sending unit to gauge |
| Black | Ground for sending unit and gauge |
| Purple | 12V power for gauge |
It is crucial to follow this wiring diagram when fixing or replacing any wires. If the wiring is not correct, it can cause further damage to the trim sender or the boat’s electrical system.
How to troubleshoot wiring issues with Volvo Penta trim sender
Step 1: Check wiring connections
The first step in troubleshooting wiring issues with the Volvo Penta trim sender is to check the wiring connections. Make sure that all the connections are tight, clean, and free of corrosion. If any of the connections are loose or corroded, clean them with a wire brush and reconnect them. Make sure to use dielectric grease to protect the connections from corrosion.
Step 2: Check wiring continuity
The next step is to check the wiring continuity using a multimeter. Set the multimeter to ohms and check the resistance between the sending unit’s green/white wire and the gauge’s green/white wire. If the resistance is within the range specified by the manufacturer, the wiring is good. If the resistance is too high or too low, there is a wiring issue that needs to be fixed.
Step 3: Check sending unit
If the wiring is good, the next step is to check the sending unit. Remove the sending unit from the outdrive or sterndrive and check its resistance using a multimeter. Move the outdrive or sterndrive to different trim angles and check if the resistance changes accordingly. If the resistance is not changing, the sending unit is faulty and needs to be replaced.
Step 4: Check gauge
If the sending unit is good, the final step is to check the gauge. Remove the gauge from the dashboard and check its resistance using a multimeter. If the resistance is not within the range specified by the manufacturer, the gauge is faulty and needs to be replaced.
Conclusion
The Volvo Penta trim sender is an essential component of a boat’s trim system. However, wiring issues can cause problems with the trim function, which can affect the boat’s performance and safety. By following the wiring diagram and troubleshooting steps provided in this article, boat owners can fix or replace any wiring issues with the Volvo Penta trim sender.
