Recently had engine overhauled, after that the petrol gauge function is messed up, moves up and down as you drive and speedometer not working at all. Someone said I must check the earth wiring, but where do I find them in the engine area?

I would start by checking the fuses. here is a guide and some diagrams to help us get started. The grounds for the system are located in the engine compartment. Make sure you have a ground cable or strap going from the engine to the frame.

Please let us know what happens.
