When driving my newly acquired Triumph Spitfire I noticed that both the fuel and temperature gauges were reading low. One faulty gauge I could believe but both? Seemed a bit unlikely. Both run through a voltage stabilizer so that seemed to be the place to start.
Unfortunately the stabilizer is mounted on the back of the speedometer. Pretty much every component on a Triumph Spitfire is easy to access except the speedometer and tachometer. I removed the seats and the steering wheel to allow myself some more room. Still one has to lie down on the floor and sort of curl into a ball and poke their head up under the dash.
One mount is easy to remove but the other is well back behind several wires. I noticed I was missing half my speedometer cable so add that to the shopping list. That mini valve cover looking thing with two wires plugged into is the voltage stabilizer.
I had a spare speedometer with one could take off. The new (used) one seemed to do the trick for the fuel gauge and the temperature gauge will have to be tested at a later point.
