yesterday i wrote about the dash lights problem, and when i was driving home i noticed that the lights turned off, the usually flickered dim, and when i pulled to a red light the tach and speedo went dead, the speedo works when moving but jumps a bit when the car is still, i was wondering if this is still an alternator problem or a short somewhere in the instrument cluster, the radio died at the same time as the tach and speedo, all fuses are good, this happened after a particularly foggy night, any help would be great, thanks in advice
