| Post subject: | fuel gauge goes down |
Hello i'm having a weird problem with my fuel gauge. It seems that when i turn the car on the fuel gauge move's along to what i think is about right but when i'm driving it starts going down, then when i stop at say some traffic lights it starts to rise again? I have a spare voltage reg that i've tried swapping over and get the same result. Its a round nose center speedo type. Anyone have any ideas? Thanks for the help

Alternator has issue i would say. You are getting voltage drop when you drive. |

I would be interested in your findings as I have a 73 mini van which has the same problem. |

Mine's doing the same thing at the moment -- fuel gauge goes up, fuel gauge goes down. I'm replacing the alternator next week, as mine is on the way out.. I'll let you know if the problem goes away. |

My fuel gauge goes down as I drive as well, however it doesn't go back up until I fill it.

Mine did that for years. The faster I went the lower it read. Then you stop, and watch it come up.... 
But I could put it up on stands in the garage and run it at 50 or 60mph and it never went down. Had me stumped, until... I decided to try a new 10V electronic voltage stabilizer, as I had one of Wombat's here. IT FIXED IT.
It seems the problem was that the old ones are a vibrator similar to a blinker can- road vibration under way reduces the output voltage when they get old. So the gauge reads lower with speed. So I flung the old one far, far away. 
PM Wombat for a new one, I bet it fixes it. |

i keep hearing about wombat's fancy voltage stabilizers, i think i'll give it a try i'm a bit curious. PM'd wombat, i'll post the results. thanks for the help. |
