Is this a Volt meter or an Amp meter?

It is from a Jaguar.
How do I connect it.
The Green wire I know is Neg
The Green/Black ??
The Black ??

its a voltmeter,the live needs to go to the fuse box feed or battery + to sense all loads

3 wires
1 off them negative (you know the one)
1 off them positive ( the gauge needle will rise)
1 off them for the backlight ilumination (the light comes on)

So connect the negative to a battery and then 1 of the other wires to the positive. If the light comes on then that wire needs connecting to the sidelights if the gauge rises then the wire needs connecting to the ign side if the fuse box (you could fuse it for safety if you want)

As usual this is in my opinion and I will accept no responsibilty for anything that goes wrong. I am made of teflon and poo doesn't stick to me.

Hope this helps you out mate.

One of my pictures got lost in the net.
I will try again.
What is the little blue thing and the little box with the green wires attached?

The backlight is a sepperate holder.

Thanks so far.

that box looks like a voltage stabaliser,used for fuel/temp gauges so not part of voltmeter

The box is a voltage stabiliser, as already stated, and not required for a voltmeter. The blue thing looks like a capacitor. Are we looking at the back of the voltmeter, or a different gauge?
The capacitor could be fitted to act as a radio suppressor, how is it wired?
Cheers John

the blue thing is earthed under the knurled nut in the middle of the guage.
The other side is joined with the plain green wire on one side of the guage(-)
The plain black wire to the other side of the guage and the G/B to another terminal on the voltage regulator. I bought the guage with these wires on.
Say the person stipping the guages incorrecly placed the fuel guage retainer on the Volt meter, how does this get wired into the fuel guage?

The voltage stabiliser has three connections, I, goes to one side of the gauge, B, goes to a live terminal that is live when ignition on. The E terminal is connected to earth. I haven't seen a capacitor used before.
Cheers John

it looks like the capacitor is connected to the live of the bulb does it not (strange).
Perhaps a photo with the stabilizer removed might help us decide whats what.
I would agree that all thats required is a live and earth to the volt meter ( Only cause thats all i've ever seen mind you)

What you have is a gauge, and a voltage stabiliser, as has been said above.

The voltmeter wires up to switched power(unless you want it reading at all times), earth and dashlights/sidelights.

The stabiliser I have recent experience with. It puts out a lot of RF interference, and can cause serious problems with electronics as well. I'd say that the capacitor/condensor has been added to damp the stabiliser. Best off to bin the thing, and use the electronic alternative.

Oh, and the output of the stabiliser should not be connected to the voltmeter.Obviously, but not to some.

Hope this helps. It is definately a capacitor 1Micro Farad and 150 V DC.
The voltage stadiliser has 2 terminals "I" and "B".

The I & B terminals are as I already stated, the earth is connected to the body of the stabiliser, usually when it is fastened to a gauge that has the body connected to earth already. Forget about the capicitor, a previous owner has added this because of some form of radio interference, or something similar.
Cheers John

And this stabilizer should be used on the Fuel guage.

Is this correct?
