temp & oil gauge not working

terry said

thanks for everybody's great input. well today with the help of a service manual I traced the 2 wires ( oil pressure & water temp) thru the bulkhead (still blinking) up to the round connector that fits into the circuit board for gauges. the wires did blink as I tested them in the round connector. I have not pulled off the connector BUT what I did not see was the usual voltage limiter anywhere. the only device I have in that area is a round condenser looking device that has 1 wire that plugs into the circuit board next to the water temp gauge and it has 12 volts when the key is on. is this my voltage limiter. looks nothing like all the squire limiters that I see with 2 wires.

That pulsing originates from the third post on the fuel gauge. Not surprised you see it at the sender connections and through the bulkhead. Sounds normal but!
That is a radio noise condenser and it plugs onto one side of the three prong fuel gauge. “Like said “ the voltage limiter is built inside the fuel gauge. You can have your gauges rebuilt or replace them with more modern quick re-acting units and a newer electronic limiter. Your choice of original style cluster gauges or aftermarket mechanical units installed as you please. A-body Rally dashes are not the same as the lower models. There are several options available to keep the original and have a updated electronic regulator. You just need to decide what way you want to go. I choose to go fully new old look in the cluster and are very happy with my decision!
