BlankSeems as if there is an opportunity here for an inventive electronics person to market a little black box that sits between any alternator and any tachometer. Pulse counter on the inputs, pulse generator on the outputs, manual control of the rate ratio. The tachometer would love a train of nice clean pulses at a constant voltage!

This is exactly what the VDO programable tach does... it's just built in to the tach. Scott Welch FirstClass Product Manager www.firstclass.com Those who make no mistake rarely make anything.

REPLY The real MCcoy would be cheaper and more reliable. Using the alternator was a cheapie shortcut used by automotive engineers to save money not improve the design. Why do people insist on using cheap shoddy alternative to doing it right. Especially when the right way is no more expensive. As Larry says, there are any number of programmable tachometer solutions available that do not use the alternator. Arild
