You can also use a tach calibrator like the one RT Engineering sells. Attach the DC connections to a 12V supply and the calibrator to the input. I had an old one I cobbled from a filament transformer and a capacitor to simulate the engine but due to CRS I cannot remember where it is to tell you how to make it. Is that a B3 cuda with black vinyl? Mine is B3 with white top and stripe. Craig
