speedo524



I wanted to test the work before reinstalling the cluster in the car. A handy substitute for a turning differential is this common wall transformer. The voltage is not critical, because there is a good signal conditioner in the input circuit of the speedometer, but this unit says it is rated at 5V AC output. A DC unit might work as well, not likely being filtered, but I can vouch for the speed calibration offered by the 60Hz AC source.
