How to Install a Volt Gauge in a Car
A volt gauge is a device that enables you to keep a close eye on the electrical system of your vehicle. These gauges tell you if the voltage drops in your vehicle. You will also be able to know if there is a problem with your alternator or your battery, which is why having one installed is so important.
Step 1 – Trim Panel
The first thing that you are going to have to do is get rid of the trim panel that is on your dash to prepare it for the volt gauge. You will do this by turning your key on and then putting your car in gear. Once you have done this, you are now ready to pull the panel off. After you have pulled it off, you can put your vehicle back into park and then turn off your key.
Step 2 – Drill
After you have removed the trim panel, you will now need to locate a spot on it where you want to drill a hole for the new gauge. This is where you will mount your ammeter. You will use the hole saw and the drill to do this step. You need to make sure that there is not going to be anything behind the trim panel that may cause any issues after you have put the gauge in its place.
Step 3 – Disconnect
It is very important that you take the time to disconnect your battery before you do anything. You will first need to make sure that you disconnect it at the negative terminal before moving to the positive terminal. The open ended wrench will be what you need for the job.
Step 4 – Wire
Once your battery has been disconnected, you are now ready to crimp the yellow ring terminal. In order to do this, you will need to get the end of the 10 gauge wire sectioned. Use your wire crimpers and wire strippers for this job. Once you have done this, you will need to run a 10 inch gauge wire through your engine bay and in through the firewall. You will do this by using the factory grommet. The line will need to be secured thoroughly by using zip ties as you go.
Step 5 – Ammeter
You will now need to get the ammeter installed into the trim panel. This is going to be the volt gauge. After the volt gauge is installed, you are ready to re-install the trim panel. In order to reinstall the trim panel, you will simply need to go in the reverse order of the disassembly. From there, run your 10 gauge wire into the back of the ammeter.
Step 6- Test It Out
Now that's the volt gauge is installed, you can reconnect everything and turn the car on to test it out. You may need to run it around the block to get an accurate test.
