How to Wire a VDO Marine Tachometer

Installing a VDO marine tachometer is an easy process that requires just a few steps. To ensure the proper functioning of the tachometer, it is important to correctly wire it. Understanding the wiring diagram is critical in getting your tachometer to work correctly. To help you with this task, we offer a brief guide on how to wire a VDO marine tachometer.

Tools and Supplies Needed

To wire a VDO marine tachometer, you will need the following tools and supplies:

  • A VDO marine tachometer
  • 16 gauge stranded wire
  • Wire strippers
  • Screwdriver
  • Wire nuts

Step 1: Prepare the Wires

The first step in wiring your VDO marine tachometer is to prepare the wires. Begin by stripping the insulation off the ends of the two tachometer wires. Make sure you leave about 2 inches of bare wire exposed. Next, strip the insulation off the end of the 16 gauge stranded wire. You should also leave about 2 inches of bare wire exposed.

Step 2: Connect the Wires

Once the wires are prepared, connect them to the tachometer. Take one end of the stranded wire and connect it to the positive terminal on the tachometer. Take the other end of the stranded wire and connect it to the positive terminal on the power source. Then, take one of the tachometer wires and connect it to the negative terminal on the tachometer. Finally, take the other tachometer wire and connect it to the negative terminal on the power source.

Step 3: Secure the Wires

Once the wires are connected, use the wire nuts to secure them. Make sure the wire nuts are firmly in place to ensure a good connection. It is also important to make sure the wires are not in contact with any other metal parts. If the wires are in contact with any other metal parts, it could cause a short circuit.

Step 4: Mount the Tachometer

Once the wires are connected and secured, you can mount the tachometer. Use the screws provided with the tachometer to mount it in the desired location. Make sure the mounting location is in an area that is not exposed to direct sunlight or any other kind of extreme weather conditions as this could damage the tachometer.

Step 5: Test the Tachometer

Once the tachometer is mounted, turn on the power source and test the tachometer. Make sure the tachometer is reading correctly and that the needle is moving smoothly. If everything is working properly, you can move on to the next step.

Step 6: Connect the Tachometer to the Ignition Switch

The final step in wiring your VDO marine tachometer is to connect it to the ignition switch. To do this, connect one end of the 16 gauge stranded wire to the positive terminal of the ignition switch and the other end to the positive terminal of the tachometer. Connect the negative wire of the tachometer to the negative terminal of the ignition switch.

Conclusion

Knowing how to wire a VDO marine tachometer is essential for ensuring the proper functioning of your tachometer. Installing a VDO marine tachometer is an easy process that requires just a few steps. By following the steps outlined in this guide, you can easily and safely wire your VDO marine tachometer and get it up and running in no time.
