Gauge Issues

I just won an EBay auction for a 71 GTX. One of the issues with the car is the gas gauge, fuel and temp gauges don't work. Is this the result of a bad gas gauge and voltage limiter like 67 Chargers?

Hi,

I would look at the instrument voltage regulator first since none of the gauges work. Some earlier Mopars had the regulator built into the duel gauge but, the 71's used a separate plug in can type module with three prongs. Hopefully, a bad regulator didn't burn out the three gauges. That can happen too, when the regulator contacts stick closed and puts the full 12 volts on the gauges.

Can they be repaired if that happened?

Yes, the gauges can be repaired but there are not too many guys/companies that do it and I believe it's a rather pricey undertaking. The first thing would be to check the gauges out. Take a look at the top sticky posting in this section on instrument panel restoration and you will find some information on checking out gauges.
