Volt Meter Hook Up?

[cghstrojan08]

How do I hook a volt meter up? There is a +, -, and S. Thanks

[fordman]

an amp guage or a test volt meter?

[cghstrojan08]

It is a gauge that you install to tell wether or not if the car is charging or discharging. Every car has one but I just want to put another one in my truck. It is a volt gauge. Not amp.

Hook the red wire up to the 12v ignition switch and the other to a ground. Pretty much any 12v wire would give you system voltage. However, you want an ignition-switched wire so the gauge powers on when the keys are turned to the ON position.

For the lights run the wire(s) to a dash light source (ie. ashtray light) and the black to ground. Now they dim with the headlamp switch.

It's that easy.

What is the spot for the "S" wire?

[FORDification]

I don't recall specifically...did you try the manufacturer's website? Normally they'll have installation instructions there.

I found this in a junk yard. Can't find anything on the internet

Don't hook it up the guage should still read okay. I bet S is the light terminal. Make the guage work first then see if S is jumped to + that the light works.

[cghstrojan08]

There are seperate wires for the light.

That is weird then S for Sense ? But a voltmeter takes the full voltage across it but almost no current so Sense does not make sense.

post a pic of the guage and wiring.

That's still a very common voltmeter sold everywhere. From the manufacturer's website:

The lighting connection is obvious, so apparently the 'S' isn't needed. Maybe it's for calibration? Regardless, if you hook up the two wires as indicated and the lighting wire, you're all set.

S for set. It's postion on the guages is at the needles pivot the most common place on gauges for an adjustment screw.

The picture solved all.
