HELP 76 dart gas an temp gauges wont work!!!

You really need to get yourself a factory shop manual. You can order reprints or CDs various places including Ebay.

Generally, there are several areas that stop gauges from working

The basic circuit is power from ignition switch feeds to instrument cluster, goes to the instrument voltage limiter, and that feeds reduced voltage to the fuel and temp gauge, then the sender terminal of each gauge feeds off to the senders

The connector on the cluster could have loose pins or corrosion, preventing proper voltage from reaching the cluster

The PC board on the cluster could be corroded and not properly grounded

The "socket" which the limiter device plugs into may not be making good contact

The limiter itself could be bad

The gauges could be bad

The sender wires could be broken

The senders could be unhooked or defective.

Because BOTH gauges are not working, I would immediately pull the cluster

Unhook the battery ground

This is easier if you drop the steering column. Just remove the trip below the column, remove the bolts at the floor plate, and the two or three nuts/ bolts that hold the column up. You should be able to drop the column in the seat

Reach up with your hand and find and unclip the speedometer cable. Remove appropriate trim screws and remove the cluster. Be careful with the harness.

Find a ground point on the PC board and hook a wire from there to the body.

The voltage limiter looks something like this:

You should be able to LOOK at the cluster and pc board and trace the copper conductors. Each gauge has a trace leading to the voltage limiter. The OTHER terminal of each guage leads directly to the harness connector. These terminals go to the sender.

Ground each sender terminal with a clip lead, and hook up power, turn the key to "run". The gauges should head dramatically towards full

IF not, check with a meter or light on the IVR side of the gauges to see if you have pulsating voltage. If so, try tightening the guage nuts. If no pulsing voltage, check for power coming IN to the limiter, which should be "same as battery. IF this is good, replace the voltage limiter.

IF the limiter is showing a pulsing voltage at the gauge terminals, and you have the senders grounded, you may indeed have bad gauges. Try hooking a 9V battery BRIEFLY to each gauge to see if it moves. Don't leave that hooked up any longer 'n you need to in order to check.
