gauges
i have a 1984 ford 150 inline six, my fuel , water , and oil gauges don't work . i was told that it was a voltage regulator. where is it located and what does it look like? i had the dash apart and i have an idea what it looks like , but i just want to be sure.

Glu, I know of one voltage reg. It's under the hood by the battery. It's a sq.box that is about 4x4 inches sq. It has a wiring harness coming out of it. It should be positioned on the radiator wall or along the side of the engine compartment near the front of the truck. That I know is a external regulator. I do belive that their are integral regulators that are on the alternator. External reg. are really easy to change and are fairly cheap. I hope this helps. Some of the other guys might have a better answer for ya...

Most likely the voltage regulator will be on pass. fender between the battery and the starter solenoid. It is there on my 83 F250. Should be under $10 for a new one.
And also for the oil guage check the wire going into the oil pressure sensor. I don't know where it in on a I6 but I beleve it is shaped like 1/2 egg with round part facing up. My wire broke righ at the connector on the motor and was not reading oil pressure.

Glu252; The gauge voltage regulator is mounted on the circuit board that forms the rear of the gauge cluster itself. Its small, about 1.5" long and maybe .5" wide. The purpose of the regulator is to provide a stable voltage for the gauges. The truck battery voltage fluctuates from less than 12 to more than 14. If the gauges were powered directly from the battery, the gauges would fluctuate up and down with the battery voltage change. The output of the gauge regulator is some lower but constant voltage that eliminates the fluctuations.
