The Ford Barn - View Single Post - 12 volt tach on a 6 volt positive ground system

There already are reasonably priced units available to run the old "meter" tachometers on 12 volts. For example, RT Engineering sells a board the goes into the old sender box for $75. I have also seen stand alone units. I surmise that the number of people out there that have a 6 volt positive ground vehicle and have one of these old tachs laying around is quite small. I would have thought that there would be a lot of folks out there that would want an alternative to a $125 Westtach 6 volt unit (which is only a 2" gauge). If we could get feedback that would justify building a few hundred of our units, we would most likely add this capability.
