Re: Tachometer fault?
Electric tachs do [B]not[B] drop to zero when the power is turned off, they sit approximately at whatever RPM's they were registering when the power (key) went off. This is normal, relax! As said above, with the power applied (key on) it should zero out until the alternator is putting out, then read something near what you expect in RPM's.
