How do I hook up a volt gauge? Jan 26, Posts: A car I recently bought came with a row of aftermarket gauges under the dash. They were all hooked up except the volt gauge, and I've never hooked one up before.

So I was hopin' someone could point me in the right direction. Thanks, Barn-core. Barn-core , May 8, Oct 28, Posts: Aug 27, Posts: Volt gauges are usually connected to the ignition circuit so it only reads when the ignition is on. Not very accurate but you will be able to tell if your charging system is working since the voltage should read between 13 to 14 volts depending on temperature. You can connect to the battery but there would be a small current draw ma all the time.

Thanks a lot guys, I'll probably try to hook it up after work today. Jul 20, Posts: Make sure that you connect the positive side of the gauge to a switched 12v source, not direct to the battery. I don't have any experience with a car set up like that, but I know for a fact that if you leave the voltmeter "ON" overnight on a C, it will flatten the battery. In a car, it may not happen overnight, but if it sits for a few days AnimalAin , May 8, You must log in or sign up to reply here.

On the back of the voltmeter, there are two connections -- one is positive and the other negative. Take careful note of which is which. Hook them up backward.

I nstalling a voltage gauge can serve many functions. It can also give you a heads up warning if your alternator is starting to go. If you installed the Casper's Electronics cooling fan harness, this gauge is vital to making sure you don't come back to a dead battery. Com You will need to decide the location to mount the gauge, but an A-pillar gauge mount is available as a professional location to mount two gauges.

You'll need to power up all of the gauges on their red wire by connecting them to the brown "gauge feed" wire in the harness. Also connect the black "ground" wire in the dash harness to each of the gauges' black wires. You will carry the tachometer signal from the coil on the purple "coil-tach" wire that runs all the way through in the sending units subharness. Polarity is not important as it is only counting pulses. Once again polarity is not an issue because these are reading resistance. The voltmeter has no sender, the gauge power and ground give it all it needs.

Proper Volt Gauge Operation

This type of gauge tells you how much and in which direction the electricity is flowing. When you turn on the lights and accessories, the voltage regulator senses the lower voltage and kicks in the alternator. If the alternator is not working or unable to keep up, the electricity flows from the battery and shows a negative reading -. A voltmeter works differently. Instead of reading electrical flow, it reads voltage.

Technical Details

When you think about the number of sensors that your engine has, it seems like there is an endless amount of gauges that can be installed to monitor their readings. Some of these readings are important, but many of them are simple inputs to the vehicle's computer. The most common gauges on today's vehicles are the speedometer, tachometer, fuel gauge, and temperature gauge. Besides having these gauges, your car will have a number of warning lights that will illuminate if there are problems with those systems. One gauge that is missing in most vehicles is the charging, or voltage, gauge.


Some late model vehicles use electronic sensors in their pressure and temperature senders for engine control functions. Before removing the original sender, we recommend that you contact your automotive dealer to be sure no critical functions will be disrupted. With pressure gauges it is beneficial to add a T-fitting to install your new gauge and to keep the warning light operational. This allows you to monitor the pressure and still have a warning light to indicate emergency conditions. Do not touch ignition wire to the sender 5 terminal on back of gauge or the sender may be damaged. These gauges can be mounted in-dash or in Auto Meter mounting solutions panels, cups, pods, etc.
