When it comes to measuring electrical current in your vehicle, having an amp meter is crucial. An amp meter is used to measure the current flowing through a circuit and is often used in car audio applications or when installing additional lighting. In this article, we will be going over the proper wiring diagram for a 12V amp meter installation.
What You Will Need
Before we get started, you will need a few things:
- Amp meter
- Fuse holder
- 30-amp fuse
- 10-gauge wire
- Wire cutters
- Wire strippers
- Ring terminals
- Crimping tool
Step One: Disconnect the Battery
Before you start wiring your amp meter, it is extremely important to disconnect the battery. This will prevent any short circuits or accidental electrocutions. Make sure the battery is completely disconnected before moving on to the next step.
Step Two: Install the Fuse Holder
The first step in wiring your amp meter is to install the fuse holder. This will protect your vehicle from any electrical shorts that may occur. The fuse holder should be installed as close to the battery as possible.
Step Two A: Cut the Wire
Using your wire cutters, cut a length of 10-gauge wire that will reach from the battery to the fuse holder. Make sure to leave enough slack so that you can crimp on the ring terminals.
Step Two B: Strip the Wire
Using your wire strippers, strip about 1 inch of insulation off of each end of the wire.
Step Two C: Install the Ring Terminals
Slide a ring terminal onto each end of the wire and crimp them securely. You may want to use a crimping tool to ensure a tight connection.
Step Two D: Install the Fuse Holder
Take the 30-amp fuse and insert it into the fuse holder. Then, attach the ring terminal from the positive side of the battery to one side of the fuse holder. Finally, attach the other ring terminal to the other side of the fuse holder.
Step Three: Install the Amp Meter
Now that the fuse holder is installed, it is time to install the amp meter itself.
Step Three A: Cut the Wire
Cut another length of 10-gauge wire that will reach from the fuse holder to the amp meter. Make sure to leave enough slack so that you can crimp on the ring terminals.
Step Three B: Strip the Wire
Using your wire strippers, strip about 1 inch of insulation off of each end of the wire.
Step Three C: Install the Ring Terminals
Slide a ring terminal onto each end of the wire and crimp them securely.
Step Three D: Connect the Amp Meter
Connect one ring terminal to the positive input on the amp meter. Then, connect the other ring terminal to the side of the fuse holder that is not connected to the battery.
Step Four: Reconnect the Battery
Finally, it is time to reconnect the battery. Make sure all connections are tight and secure before turning the key. Once the battery is reconnected, turn on the car and check the amp meter to ensure it is working properly.
