The Herald is coming along. We trailered the car to the Las Cruces, NM show a few weeks ago. We were pleased to be recognized with a nice photo and frame.

The problem: the gas gauge shows "full" when the ignition is on and when the car is running. I disconnected the wires at the tank and the gauge still shows full. Could this be a bad ground at the gauge, an bad voltage stabilizer, or a faulty gauge?

We can take the car on longer trips, now that the leak in the caliper is fixed, but not knowing the fuel level is not safe, either.

T.T.
 
I suspect you have a wiring issue. Look on the Spitfire and GT6 magazine site. Gives a good explanation of the
most likely faults and how to fix them. Probably a short.
 
I agree with some wiring "issue" upstream of the sender; something is providing "full power" to the gauge when the ignition is on? You likely do NOT have a voltage stabiliser in your gauge circuit (if you did, the fuel gauge needle would be red instead of white), so I'm pretty sure that can't be the problem. ;)
 
Thanks for you help. I will pull the speedometer and such out of the dash and trace wires. I thought the car had a voltage stabilizer- the current going to the temp gauge is ten volts.

You'll see the voltage stabilizer screwed to the back of the speedometer if it has one.

Interesting! I thought I remembered your car being too early a Herald for the stabilizer circuit? What does the temp gauge look like: does it have a "solid" white arch between C and H or is it a "broken line"?
 
I'm not sure the temp gauge is original to the car. It is a solid white line. Rimmer Bros. said the numbers on the car are consistent with a 1965 export car. At this point Herald work has stopped to prepare the Spitfire engine to go to the machine shop- low oil pressure, bearing noise on start-up, and black stuff on the rear valance.
