Triumph TR4 - Smiths/Jaeger Classic Gauge Calibration | Roundtail Restoration #tr4 #triumph

Using a bench power supply and a resistor box, I check and calibrate an old bi-metallic Smith's fuel gauge (BF2206/00). As with most things like this, if you have the right equipment, it's not that hard. And you'll learn a lot, too! Want to see all of the body restoration of my 1966 Triumph Spitfire?
