Voltage Meter

Will this work for car applications?

If not, can anyone suggest a cheap volt meter? (P.S. Not Stinger, the Ebay seller restricts sales to Canada)

Yes they will work. I got the same type for an ampere meter and it works prefect.

Great, can you give me directions on installing it? In terms of wiring.

starboy869 · Apr 24, 2009

Umm one wire to positive and one to ground ie. Metal frame, etc., They're pretty basic.

This voltage meter isn't like that. That's why I'm asking. It has 4 pins.

Autozone has one you can plug into your cigarette. I have it works great.

The one listed requires a 5V power supply. Look for another one that just has 2 wires or one that uses 4 wires but works on 12VDC.

Sorry I missed that. I know there's a ebay seller in china that sells 12v Dc meters.

I found a 12V one, but alas it has 4 pins as well. It says two for working power and two for measure input. So would I just ground the two negatives, and split the power wire from the battery into 2 wires, one to each positive (working and measure)?

The design of this voltmeter seems redundant.

Heres the link:

I found a different one now. Same voltmeter, but says it doesn't need a seperate power input.

Now, its two dollars more. Not to sound cheap or anything, but it would seem smarter to buy the first one if it'll work fine.
