I was wondering; What is the best way to test a tachometer without an engine? I am not sure if the tach was dead or if it was the sender or other wiring issue, but I don't have a car to test it on. BTW the tach was off an '84 GTV6. Any suggestions would be great, thanks.

I was checking the wiring diagram to see what color wires to hook up ( I am going to test it on another car) the three wires that hook to the rev counter (I am assuming this means tach) are labeled N, B, and what looks like, SS. what do those stand for, I am hoping colors and not simply negative, battery and signal. But it looks like N(+),B(signal),SS(-)???

the wire letters should be colors, n==black b=white (I think) dont know what ss is. there should be a ground, signal and 12 wire to the tach, not counting the light.
