Ford gauge wiring?

I am trying to wire my constant voltage regulator for my gas gauge.I have a constant voltage regulator from late 70's early 80's , the one that looks like the connections fit a 9 volt battery. The problem is I don't know which conection goes to the power and which goes to the gauge.Thanks for any and all help,Ken N.

 

You gas gauge should have two poles on the back of it, one should be marked with a + or say ignition. It gets full voltage (whatever your car has) and the other pole goes to the sender. It does not need to be wired to your regulator, any switched voltage should work.

 

the guy at united speedo rebuilt the guages on a 65 ford truck , cuz they were burnt , said for the oil , water and gas guage needs to have 5 volts coming off the instrument voltage regulator on one pole , dont matter which one , then the sender wire goes onto the other pole .on the regulator , it is marked ign for constant power , the other is marked ins , for the three gauges . do not mix the wiring ! you will burn the gauges ! before you hook the gauges up , check for voltage coming off the regulator , if it has a constant 12 volts , dont hook the gauges up , these regulators burn up also ! if your gauges dont work , they are probably burnt also !

 

A little known fact is that guages for fords up to I believe 1965 were the same as the 40s justthe face plate changed. If I'm wrong please punch me square in the ***. I used ford guages in a 50s International by changeing the face plates that come out of a econoline from the 60s.

 

Thanks for the quick replies. Other boards could not answer. Nice to be on the H.A.M.B.Thanks guys!

 

Then wouldn't that be called a resistor?

My '65 Galaxie had 12 V run to the gauges, they were clearly marked + on one side and - on the other side. There was no special gauge regulator anywhere on the car. I guess some fords have them and others don't?

 

the guy who fixed the cluster , told me to buy an instrument voltage regulator . it worked out just fine !

 

Ditto-I used 70's ford truck gauge movements in my 41 ford cases but I used the reg. that were on the 70's gauges. The 70's gauges operate off 6-8V I believe.
