need help wiring fuel gauge

this is the fuel gauge for my 1950 chevy car.

i now am running 12 volts and bought this Fuel Gauge Reducer .

my problem is i am not sure whcih wires go where?

a wire from the battery to which terminal? and a wire from the sender in the tank to the other?

and where do i put the reducer?

there is no ground terminal, so i assume it is grounded by mounting it?

any help is appreciated.

I am not familiar with the voltage reducer shown; but the reducer always goes in the power
line so the gauge receives the reduced voltage.

 

That looks like a resistor, it would be installed in series between the power wire from the ignition switch, and the power terminal on the gage. The sender should be connected to the sender terminal on the gage.

The broken piece of red paper used to say I and S on it....I forget which side is which.

 

Power (through the reducer as RichB and squirrel said) to terminal B, sender wire to terminal A. See the remains of the red tag on A, this is what it said.

 

Oh....different from the later 50s gages, thanks for the info!

 

you guys are awesome!!!

thanks again

If you put it in the power it will effect both gauges

 

Water temp and oil should be mechanical gauges, ammeter wiring does not change.

 

Could be a simple 6V zener diode, that will drop 6V across it, leaving 6-8V depending on the charging voltage at the battree. If it has a band on one of the terminals, that side will go to ignition terminal of ignition switch, other side (no band) goes to power terminal of gauge. This applies to negative grounded 6V systems.

 

Kinda doubt it's a diode, they don't have the bulge at the ends like resistors do....

 

24 riverview is right the temp gauge is mechanical I can't believe someone cut the capulary tube

 

Ever try running the gas gauge with the original instrument voltage regulator using the 12V. If the IVR is still there, it may be possible that it would still regulate to 5V or so, even with the 12V.

 

I've run several 6V gas gauges on 12V. I've never put a reducer or resistor in and they all worked fine. I was under the impression the gauge wasn't concerned anout voltage. Only resistance.

 

Chevy didn't use an instrument voltage regulator.

 

Find Fifth Avenue in Kansas on the internet who makes the Runts resistor then go to Tech Tips and Randy Rundle explains everything you want to know about where and how to use the resistor. Good stuff.

 

U R CORRECT, but should work with Ford and any other car with Ford type IVR.
