The Wire Assembly Diode Vdo Tach carries the tachometer signal from the engine to the VDO instrument display on the FS4400 floor saw. The diode within the assembly conditions the signal, protecting the gauge from voltage spikes that could cause erratic readings or instrument damage. When this assembly degrades or fails, operators may experience an inaccurate or non-functioning tachometer, making it difficult to maintain optimal engine speed during cutting operations.
