All of the other guages work fine. The alternator guage swings back and forth until the engine picks up RPMs, but thats it. I havent looked into the guage or anything. i dont exactly know what i would be doing there.
I have replaced the sending unit, wire, and guage for my fuel system in my 74 dodge dart. when i fill it up it reads 3/4 and is on the E about 4-5 gallons later. Can anyone help me here?
