It could be a bad/loose connection anywhere between the motor and the tach. This includes the plugs that go into the back of the Instrument Panel and the connections of the tack into the printed circuit. It is also possible that the tach is bad. The ground wires near the horn are actually attached the the front left radiator support where it attaches to the frame (at least that is where they are supposed to be). I do not think it will be a system problem, if it was then you would probably hear the motor "skip a beat". It is most likely a problem with the tach circuit itself. Does it flicker in any pattern or is it random? David Teitelbaum vin 10757 --- In dmcnews@xxxxxxxxxxxxxxx, "drdhdmd" <doctorDHD@xxxx> wrote: > > > OK, I checked and cleaned fuse #1.
