ok help is needed again.
I have a vdo guage 6-180 ohm and sender 6-180. has anybody got the diagram as to why when connected there is no change in the guage and i have checked the sender and it is ok..... help hate electrics

Oil temp ? I thought mine wasn't working but on closer watching the needle just didn't move far as the oil doesnt get hot enough

I'm assuming fuel gauge in your 1500 beetle

Is the voltage stabiliser working?
If so, hook up the gauge while out oh the tank, make sure you run a tempory earth and operate it through the range, should make the gauge react. Or try earthing the sender wire without the sender, will make the gauge go full scale.

tried earthing the guage without the sender but it still wont move over the empty ? it is definatley 12v (well has it printed on it) and i can check the sender and i get 6-180 ohms across the unit.
??????????????????

Gauge must be earthed, sender must be earthed, 12V supply to voltage stabiliser (also earthed), pulsing 12v out of stabiliser and into gauge, then earth the sender wire and the gauge will react. Then connect the sender to the gauge with the body of the sender earthed you can then move the float and the gauge should react correctly.

Easy

Also when the sender is in the tank, it must have a good earth.

cheers mat will try tomorrow happy xmas

I had to add a wire to the one of the sender screws to earth it out as My tank isn't earthed..

My tank sits on blu tac.. lol..

not common I know... lol

yes it was all down to a sh@#ty earthing.
thanks to all and happy xmas to all that have helped me this year

Yippie.

Merry Christmas Clyve
