I posted a topic a while back about my fuel gauge when i turn the car on it sits still but when i drive it starts to go down.

I've just fitted one of wombats Voltage Regulator and it still doing it.

I connected a test light and i get a signal out of the Dark Green, when the car is on and i put the test on the back of the fuel gauge the dark green has no signal but the light green does.

its a 65 round nose, with the center mounted speedo and fuel gauge all in one.

Any help would be great, thank you.
