Ford focus 2002 gauges

Hi does anybody know why my petrol gauge and temperature gauge have started showing a reading with my ignition switched off after about 10 minutes also my battery seems to be going flat are they related

Could be related, if something isn't switching off when it should. I suggest you get somebody to do a residual current test - or do it yourself if you have the necessary skills and equipment.

hi thanks for info i will try and do a ridual test i have got a multymeter and beleave you put it in serous with live across and see if there is any drain though battery

[GreenV8S]

If you do it that way, make sure you short the leads together while you complete the circuit to protect the meter from the inrush current.

A more convenient way to do it is to measure the voltage drop across each fuse. Fuses have a small but predictable known resistance and if there is a current through them they produce a voltage drop large enough to be measured.

The gauges are a common MK1 Focus trait. Not too sure why they do it, possibly something to do with a faulty dash cluster. My ST170 has done this for years, I just learnt to live with it.
