The dealer is stumped and has been unable to resolve the no sweeps at start up. And it has been progressive and alternating. Alternating or intermittent with whether the speedo would function at all. There may or may not be a functional speedo over a period of time but most recently it functioned, even though initially there were no sweeps with either the speedo or tack. Early on, speaking of progressive, the tach would sweep though that no longer ws the case. In other words, no absolutes. The dealer says no ignition switch issue. Their conference with Triumph has lead no where. Any suggestions?
