Hi there,
I am reasonably good at electronics and working on cars, but i have a fault with my vauxhall corsa.
The fuel gauge is bouncing when driving along.
I have shorted two wires together, and this makes the gauge go right up to full, and then i disconnect this jumper wire the gauge falls to nothing.
Once connected the wiring must be supply a resistance to the fuel gauge as it moves the needle, it is only once driving that this fault occurs.
I have read on the internet this seems to be a reoccuring fault with this model of vehicle.
I have also read changing the sender unit doesn't always cure the fault.
So I am wondering is there a circuit i can make, or a circuit that already exists that would:
Take the resistance over a period of seconds / minutes, and then put out an average resistance rather than a constantly changing one?
This is something which i am guessing would have to be computed by a microcontroller or some such?
Has anyone got any advice?
Cheers
Paul
