My speedo's just packed in on the way to work, had odometer stop before and changed the clocks but the speedo goosed this time. Gonna start with the clock first as they're cheap but worried it may be the sender. Its a 2000 Corsa B with electronic revcounter & speedometer, rev counter still working though, do they run off the same sender? Any help would be appreciated as gotta drive through regular speed traps on my journey home, not good. :(:o
