Re: Official RYCA CS-1 Updates

I'm wiring up the tach and speedo. According to RYCA's instructions, the black wire is ground, the red wire is +12v for the light bulb, and the blue wire is +12v to power the tach, and the green wire is the voltage pulse from the coil.
When I hooked up just the red and black wires for the tach and speedo to just test the lights inside the cases, both lights lit up, but the needle on the tach snapped all the way to the right and quivered. That doesn't make sense to me.
Why would the needle move from just applying 12v to the red wire?
