Right been having lots of elec problems latley in the saph 4x4, to the point were i have fitted an extinguisher

. The latest problem is when driving along the dash light will light up on the panel above the stereo (door lights, low fuel light, low temp etc) they will all come on for a bit then go off like when u turn the ignition on. Car runs mint at last just really irritating me. Any ideas???
