Instruments not working
The car run fine. The speedometer works but the instrument gauges ( Bat. fuel, oil pressure) do not work. Could it be a fuse on the ignition under the dash that is blown? Or is it something else? It is on a 1950 Ford tudor Thanks

Re: Instruments not working
Power supply is most likely There is a little thing called an IVR (instrument voltage regulator ) on the back of the cluster . They are squareish and about one inch by one half usually with two studs for the terminals. Power comes in and then out to the instruments. My guess would be yours is defective. Tim

Re: Instruments not working
Looking at the wiring diagram the instruments get their power from
the ignition switch, black wire with green tracer. |
