Fuel gauge problems in 68 beetle
I have been trying to get the fuel gauge going in my brothers beetle and have found a diode or capacitor or resistor or SOMETHING that seems to be the
problem.
Originally the wiring loop is such that power goes to this thing, then to the fuel gauge. The ground off the gauge goes to the sensor and the sensor
is earthed. Like this the gauge always shows empty.
If i remove the thing and put the power wire straight to the gauge it always shows full.
This thing is obviously broken but i have now idea what to ask for at the auto sparky. Is it something to do with the previous owner changing from 6
to 12 volt????
Help!!! I'm sick of running out of fuel.
Here is the THING.

You will only get a S/H one from a VW shop there not made new any longer
You may have to try several to get one that works.
Its nuthing to do with the conversion as they were built for 12volts and your still running 12 through the unit
If you have a 6 volt sender unit in the tank you may want to look out for a later 12volt sender as there will be a variance in the reading and you
can not adjust that you will have to calibrate the fuel cauge by your fills at the service station know what level the tank is at and whats in
the tank itself

12 volt sender as far as i know, it is new.
The voltage regulators are standard stuff for 12volt cars and are sometines called a voltage resistor.
There are threads about 6-12volt stuff i think you need a ballist resistor or something.

thought i had it fixed but sadly no.
Interesting result though, the gauge varies according to engine revs
i may have just stumbled on a cheap tacho hehehe
looks like there is a short somewhere and the voltage regulator is sensitive enough to pick it up.
Any auto electricians on this forum?
oh and the sender ended up stuffed, it melted, not good since its in the tank!!!!
