What a deal On a Digital Voltmeter ?

I've got a new out of the box LED that says 12.7 volts always.

If anyone wants it, it's for sale for $10,000.00 hard cash.

How can you beat having always-full batteries?

Anyone who trusts a battery bank worth 300 times more than the untested instrument is, ah, er, ahem "brave". Yeah I guess that one will get past the censors.

I'd bet theres more to it than that.
I'd bet he's an ebayhater.

I've bought a few of the cheapies. If you don't mind if they're off by 10%, they're fine. The Sears product looks like it has actual wires. Mine has thread.

Off by 10%? that's 1.2 volts on a 12 volt scale. The difference between fully charged (12.6V) and very dead (11.34V) I wouldn't even accept 1%.

Between cataract and glacial reaction time I no longer drive at night. I want talking gauges so I don't have to take my eyes off the road.

"Oooooh help me - I'm soooo hot"

"I am in pain! I need more lube!"

"I've slipped out of my belt. Pull over"

But then again I am a widower. Married guys would risk having the DW set hammer to dashboard.

If we live long enough, we will have that. Everything will have a chip and voice software.

Hey Mr.MEX, get your glasses with anti-glare and it will help night driving. Marvin

I've got two of the Mini voltmeters very similar to what RJ posted, on my Dashboard. One for engine and one for house battery, even though i can use either battery for wither duty at the turn of a switch

Except I bought the 3 wire versions. I put the 3rd sense wire directly on the battery(+), and then used the calibration screw to dial them in with my DMM on the battery terminals too. These come on only with my ignition. if I had only the 2 wire models I could not wire them directly to the battery(+) unless I wanted them on all the time, or wanted to manually switch them on or off.

If I wired a 2 wire voltmeter to come on with my ignition, then it would not be reading battery voltage but the voltage at the circuit I tapped into which is live with the Key ON. Less accurate.

I bought the green ones. Way too bright at nighttime on my dashboard. I used 2 layers of 35% window tint to calm them down. Can still easily see them in daytime.

I am going to replace them with Red 3 wire voltmeters as the rest of my Dashboard lighting is red.

I spent about 7$ for the 3 wire versions on Amazon, but they get here in 2 days.

Single conductor 26-gauge wire does not make it a cable. A 24 gauge stripper does not strip the wire and a 26 gauge telecom stripper does not nick the conductor when stripping. I've got 3-1/2 digit gauges that increment .4 volt up or down. So they can be classed as .8 volts + -

One of the best of the gauges is an LCD meter called a VOLT MINDER. It is a low voltage alarm that someone here on this forum clued me into several years ago. Three and a half digit impressive sampling rate and it has endured a lot of use. It is linear inaccurate but liveable with a .07 error @ 14.00 volts. Of course the meter is no longer available :(

The new to me 4.5 digit volt meter is accurate. Only time will tell if it remains accurate.

These are what I got. Teeny wires, they differ by 0.2v on the same circuit, and they're both too high according to my VOM.

It's not rocket science so I accept that I got what I paid for.

I have bought several in the frames....like the dead link posted, but they are not nearly as brite as the minis. I put one in my boat, and can't see it most times. I also have ac and dc matching in the MH, both hard to see in brite daylite. So I always buy the minis, much better.

Secondly, I don't know where all this inaccuracy is coming from, but I haven't had any vari by more than 1/20th v.......1/2 of the 1/10th digit, and most are much closer than that.
Thread for wires ????? never happened. They have all been very consistently good. I did have 1 failure in all I've bought (15),.....only the center bars lit right out of the box.

These have went up a lot in price. I used to buy these much cheaper.
I bought one for 37 cents including shipping. I posted the link to that one here.
And most all are burning day and nite 365.
