Are you looking for a reliable guide to help you install your Sunpro Super Tach 2? Look no further! In this article, we’ll provide you with step-by-step instructions on how to install and wire your Sunpro Super Tach 2. But first, let’s start with the basics.
What is a Sunpro Super Tach 2?
A Sunpro Super Tach 2 is a tachometer that measures the revolutions per minute (RPM) of an engine. It is commonly used in vehicles to monitor engine performance and diagnose issues. The Super Tach 2 is a popular choice among car enthusiasts because it is easy to install and provides accurate readings.
How does it work?
The Sunpro Super Tach 2 works by using a sensor that reads the electrical current from the ignition coil or spark plug wire. This information is then converted into an RPM value, which is displayed on the tachometer’s face. The tachometer also has a shift light, which can be set to illuminate at a certain RPM to help the driver shift gears at the right time.
Why install a tachometer?
Installing a tachometer can help you identify potential engine problems by monitoring the RPMs. A tachometer can also help you improve your driving performance by allowing you to shift gears at the optimum RPM range. In addition, tachometers can add a stylish and sporty look to your car’s interior.
Tools Needed
Before we start, you’ll need a few tools:
- Phillips head screwdriver
- Wire strippers
- Crimp connectors
- Electrical tape
- Drill and bits (optional)
Step-by-Step Instructions
Step 1: Disconnect the Battery
Before starting any electrical work, it’s important to disconnect the battery to prevent accidental shocks or damage to your car’s electrical system. Use a wrench to remove the negative battery cable and secure it away from the battery.
Step 2: Mount the Tachometer
Decide on the location of your tachometer. The most common places to mount a tachometer are on the dashboard or steering column. Once you’ve decided on the location, use the provided bracket and screws to securely mount the tachometer.
Step 3: Run the Wires
Route the wires from the tachometer to the engine compartment. The tachometer should come with a wiring diagram that you can use to identify which wires go where. Make sure to leave enough slack in the wires so that it doesn’t pull tight when the engine is running.
Step 4: Connect the Wires
Connect the wires according to the wiring diagram. The red wire is the power wire, which should be connected to a switched 12V source. The black wire is the ground wire, which should be connected to a clean, bare metal surface. The green wire is the signal wire, which should be connected to the negative side of the ignition coil or tachometer output on electronic ignition systems.
Step 5: Test the Tachometer
Before finalizing the installation, test the tachometer to make sure it’s working properly. Reconnect the battery and turn on the engine. The tachometer should read the RPMs of the engine. If it doesn’t, double-check your connections and wiring.
FAQs
What should I do if my tachometer reads too high or too low?
If your tachometer is reading too high or too low, it may be an issue with your engine’s ignition system. Check your spark plugs, coil, and distributor for any issues. If everything looks fine, adjust the tachometer’s settings according to the manufacturer’s instructions.
What if my tachometer doesn’t have a shift light?
If your tachometer doesn’t have a shift light, you can use the RPM readings to manually shift gears at the optimum RPM range. The ideal RPM range varies depending on the engine and driving conditions, but a general rule of thumb is to shift between 2,000-3,000 RPM for normal driving and 4,000-5,000 RPM for high-performance driving.
What if I’m not comfortable installing the tachometer myself?
If you’re not comfortable installing the tachometer yourself, it’s best to seek the help of a professional mechanic or auto electrician. They have the expertise and tools necessary to properly install and wire the tachometer.
Conclusion
Now that you know how to install and wire your Sunpro Super Tach 2, you can enjoy accurate RPM readings and improved driving performance. Remember to always follow the manufacturer’s instructions and use caution when working with car electronics. Safe driving!
