The spot lights on my S1 have decided they are not going to work any more. I have changed both bulds, still no joy, if I use a multimeter it shows there is over 12 volts there with the engine running and the lights on full beam. When I put the bulb back in the circuit the multimeter reads 0 volts or lo. Could it be a bad earth, if so were are the spot lights earthed.
Thanks
